Course Content
Computational Statistics is the area of specialization within statistics that includes statistical visualization and other computationallyintensive methods of statistics for mining large, nonhomogeneous, multidimensional datasets so as to discover knowledge in the data. As in all areas of statistics, probability models are important, and results are qualified by statements of confidence or of probability. An important activity in computational statistics is model building and evaluation.
First, the basic multiple linear regression is reviewed. Then, some nonparametric procedures for regression and classification are introduced and explained. In particular, Kernel estimators, smoothing splines, classification and regression trees, additive models, projection pursuit and eventually neural nets will be considered, where some of them have a straightforward interpretation, other are useful for obtaining good predictions.
The main problems arising in computational statistics like the curse of dimensionality will be discussed. Moreover, the goodness of a given (complex) model for estimation and prediction is analyzed using resampling, bootstrap and crossvalidation techniques.

Literature
Audrino, Lecture Notes.
These workshop lectures are designed to introduce participants to one of the most vibrant, free of charge statistical computing environments ― R. In this course you will learn how to use R for effective data analysis. We will cover a selected range of both basic topics (e.g., reading data into R, data structures (i.e., data frames, lists, matrices), data manipulation, statistical graphics) to more advanced topics (e.g., writing functions, control statements, loops, reshaping data, string manipulations, and statistical models in R).
This course is also helpful as a primer for other summer program courses that will use R, such as the courses on Computational Statistics, Data Mining, or Advanced Regression Modeling, among other courses. No prerequisites are required for this course.
Day 1 – Fundamentals in Python: Operators, data types, control flow, style guide.
Day 2 – Introduction to PANDAS (Python Data Analysis Library).
Day 3 – Introduction to NUMPY (Numerical Python) and MATPLOTLIB (Visualization with Python).
For each topic, we solve small programming tasks in class and discuss possible solutions.
These intensive lectures provide an opportunity for a participant to initially develop, or perhaps refresh, an intuitive understanding of the concepts of basic matrix algebra (the first three days) and calculus (the final day). The ultimate goal is to develop a sufficient level of understanding of these foundational mathematical tools that will allow a participant to adequately comprehend and successfully apply them in subsequent GSERM coursework. In addition to the lectures, problems and solutions will be provided to enhance the learning process and provide for selfevaluation. It is assumed that the participants are proficient in rudimentary algebra. This series of workshop lectures carries no formal academic credit.
These intensive lectures provide an opportunity for a participant to refresh their understanding of, and familiarity with, the concepts and assumptions of bivariate and multiple ordinary least squares (OLS) linear regression. The ultimate goal is to possess a sufficient level of understanding of these topics so that a participant can adequately comprehend and successfully apply them in subsequent GSERM coursework. In addition to the lectures, problems and solutions will be provided to enhance the learning process and provide for selfevaluation. It is assumed that the participants are proficient in rudimentary statistics (e.g., basic hypothesis testing); while it would be helpful to have been (at least) exposed to OLS regression, this is not a prerequisite. This series of workshop lectures carries no formal academic credit.
Prerequisites

Prerequisites and content
Prerequisite knowledge for the course includes the fundamentals of probability and statistics, especially hypothesis testing and regression analysis. This intermediate level course assumes that students can interpret the results of Ordinary Least Squares, Probit, and Logit regressions. They should also be familiar with the problems that are most common in regression, such as multicollinearity, heteroscedasticity, and endogeneity. Finally, students should be comfortable working with computers and data. No prior knowledge of R or network analysis is required.
Instruction is split between lectures and handson computer exercises. Students may find it to their advantage to bring with them a social network data set that is relevant to their research interests, but doing so is not required. The instructor will provide data sets necessary for completing the course exercises.
Hardware
Personal Laptop
Software
The latest version of R available at https://www.rproject.org/
Learning objective
Students will learn about the motivation, logic, methods, and literature of social network analysis. They will learn how to format network data for analysis R, how to choose and estimate appropriate models, and how to evaluate the results. They will strengthen their skills in presenting and commenting on statistical research in academic settings.
Course content
The concept of “social networks” is increasingly a part of social discussion, organizational strategy, and academic research. The rising interest in social networks has been coupled with a proliferation of widely available network data, but there has not been a concomitant increase in understanding how to analyze social network data. This course presents concepts and methods applicable for the analysis of a wide range of social networks, such as those based on family ties, business collaboration, political alliances, and social media.
Classical statistical analysis is premised on the assumption that observations are sampled independently of one another. In the case of social networks, however, observations are not independent of one another, but are dependent on the structure of the social network. The dependence of observations on one another is a feature of the data, rather than a nuisance. This course is an introduction to statistical models that attempt to understand this feature as both a cause and an effect of social processes.
Since network data are generated in a different way than many other kinds of social data, the course begins by considering the research designs, sampling strategies, and data formats that are commonly associated with network analysis. A key aspect of performing network analysis is describing various elements of the network’s structure. To this end, the course covers the calculation of a variety of descriptive statistics on networks, such as density, centralization, centrality, connectedness, reciprocity, and transitivity. We consider various ways of visualizing networks, including multidimensional scaling and spring embedding. We learn methods of estimating regressions in which network ties are the dependent variable, including the quadratic assignment procedure and exponential random graph models (ERGMs). We consider extensions of ERGMs, including models for twomode data and networks over time.

Prerequisites (knowledge of topic)
The course is designed for Master, PhD students and practitioners in the social and policy sciences, including political science, sociology, public policy, public administration, business, and economics. It is especially suitable to MA students in these fields who have an interest in carrying out research. Previous courses in research methods and philosophy of science are helpful but not required. Materials not in the books assigned for purchase and not easily available through online library databases will be made available electronically. Bringing a laptop to class will be helpful but is not essential.
Hardware
Laptop helpful but not required
Software
None
Learning objectives
By the end of the course, students should be able to design, critique, and implement case study research for major projects, including MA and PhD theses.
Course content
The central goal of the seminar is to enable students to create and critique methodologically sophisticated case study research designs in the social sciences. To do so, the seminar will explore the techniques, uses, strengths, and limitations of case study methods, while emphasizing the relationships among these methods, alternative methods, and contemporary debates in the philosophy of science. The research examples used to illustrate methodological issues will be drawn primarily from international relations and comparative politics. The methodological content of the course is also applicable, however, to the study of history, sociology, education, business, economics, and other social and behavioral sciences.
Course structure
On the first day the seminar focuses on the philosophy of science, theory construction, theory testing, causality, and causal inference. Next, the seminar will look at the comparative strengths and weaknesses of case study methods relative to quantitative methods, particularly statistical methods and formal modeling. On Day 2 the seminar outlines how to conceptualize, define, and measure qualitative independent and dependent variables. It then turns to the core issues in case study research design for single and comparative case studies: identifying a research question, developing alternative explanations for the outcomes of cases, and choosing cases for close study and comparison. On Day 3 we will explore typological theorizing and its use in case selection for smalln research, and we will apply this method in exercises. This leads into a discussion of and exercises on traditional process tracing, a method of withincase analysis that uses evidence from a case to adjudicate among alternative explanations of the case. On Day 4 we will examine the relatively new method of formal Bayesian process tracing, and we will practice it in exercises. The seminar then looks at ways of combining qualitative and quantitative methods in a single research project, and it outlines field research techniques, including archival research and interviews.

Mandatory readings before course start
It is advisable to do as much of the mandatory reading as possible before the course starts.
Examination part
Research design paper (details below)
Supplementary aids
none
Examination content
In addition to doing the reading and participating in course discussions, students will be required to use powerpoint to present orally an outline for a case study research design, or a multimethod research design that includes one or more case studies, in the final sessions of the class for a constructive critique by fellow students and Professor Bennett. Students will then write this into a research design paper about 3000 words long (12 pages, doublespaced) within a month after the course.
Presumably, students will choose to present the research design for their PhD or MA thesis, though students could also present a research design for a separate project, article, or edited volume. Research designs should address all of the following tasks (elaborated upon in the assigned readings and course sessions): 1) specification of the research problem and research objectives, in relation to the current stage of development and research needs of the relevant research program, related literatures, and alternative explanations; 2) specification of the independent and dependent variables of the alternative explanations for case outcomes; 3) selection of a historical case or cases that are appropriate in light of the first two tasks, and justification of why these cases were selected and others were not; 4) consideration of how variance in the variables can best be described for testing and/or refining existing theories; 5) specification of the evidence to be gathered, including both process tracingevidence and measurements of the independent and dependent variables for the alternative explanations.
Students will be assessed on how well their research design achieves these tasks, and on how useful their suggestions are on other students’ research designs. Students will also be assessed on the general quality of their contributions to class discussions.
Examination relevant literature
The mandatory readings provide the methodological basis for writing the research design paper.
Prerequisites
Basic knowledge of statistics, data analysis, and programming.
Hardware
Participants need to bring laptops.
Software
Google Colaboratory environment (https://colab.research.google.com/). Participants will receive setup instructions before the course.
Learning objective
Large language models (think ChatGPT) are incredibly useful tools for research in the social and behavioral sciences. In this course, you will (1) learn about the fundamental principles of large language models, (2) learn how to employ opensource large language models using the Hugging Face ecosystem, (3) learn about the rich opportunities that large language models offer for behavioral and social science research, and (4) gain experience in applying large language models to answer personal research questions.
Course content
The course introduces the use of opensource large language models from the Hugging Face ecosystem for research in the behavioral and social sciences. In short lectures, participants will learn about key concepts (e.g., embeddings, causal attention, feature extraction, classification, prediction, finetuning, and token generation) and practical examples from social and behavioral science. In handson exercises, participants will apply language models to answer research questions from psychology, political science, decisionmaking research, and other fields. During and after the course, participants will engage in a personal research project applying large language models to a personal research question. Two lecturers will hold this course, implying a high level of support during the exercises and research project design.

The paper communicates an analysis applying large language models to a personal research question, including all parts of a traditional research paper (introduction, method, results, and discussion). The research paper can be based on the examples during the course.
Prerequisites (knowledge of topic)
Each student is to submit an outline (no more than 500 words in length) of a specific research question and/or a set of hypotheses that s/he would like to examine via an experimental approach. This outline (in PDF format, file name format: “LastNameFirstNameResQues.pdf”) should be emailed to ghaeubl@ualberta.ca with “GSERMEMBS” as the subject line by 23:00 (St. Gallen time) on Friday prior course start.
As part of the introductions on the first morning of the course, students be will be asked to give 2minute presentations on these research questions/hypotheses (and to say a few words about their areas of research interest more broadly).
The objectives behind this assignment are:
• to facilitate learning by ensuring that students have their own concrete research questions/hypotheses in mind as they engage with the material covered in the course
• to provide the instructor with input for tailoring the course content and/or class discussions to students’ interests
Course content
The objective of this course is to provide students with an understanding of the essential principles and techniques for conducting scientific experiments on human behavior. It is tailored for individuals with an interest in doing research (using experimental methods) in areas such as psychology, judgment and decision making, behavioral economics, consumer behavior, organizational behavior, and human performance. The course covers a variety of topics, including the formulation of research hypotheses, the construction of experimental designs, the development of experimental tasks and stimuli, how to avoid confounds and other threats to validity, procedural aspects of administering experiments, the analysis of experimental data, and the reporting of results obtained from experiments. Classes are conducted in an interactive seminar format, with extensive discussion of concrete examples, challenges, and solutions.

Examination part
Students are to complete a (2hour) written exam in the afternoon of the last day of class. In the exam, students are given a description of a research question, along with specific hypotheses. They are to produce a proposal for an experiment, or a series of experiments, for testing these hypotheses. The exam is “open book” – that is, students are free to use any appropriate local resources they wish in developing their proposal. (Here, “local” means that students may not access the Internet or other communication networks.)
Regular attendance and active participation in class discussion are expected.
Common standards of academic integrity apply. Work submitted by students must be their own – submitting what someone else has created is not acceptable.

Examination part
A written homework assignment which consists of estimating a variety of models using JAGS as well as a brief essay describing how the students would go about incorporating Bayesian methods in their own work and what they see as the main advantages/disadvantages of doing so.
Supplementary aids
Open book/practical examinations. The students should use the example code from the lectures to help complete the practical component as well as both required texts to help answer the essay component. Specifically, the linear model and dichotomous choice model examples will be very useful as well as the first 3 chapters of the Gill text and Section 3 of the Gelman and Hill text.
Examination content
Bayesian versions of the linear and dichotomous choice models, including presenting the appropriate results in a professionally acceptable manner. This includes creating graphical representations of the model results as well as a thorough discussion of how to interpret the results.
For the essay component, students will need to be aware of the benefits of the Bayesian approach for their own research (or the lack thereof) and to describe, in detail, the types of choices they would need to make in order to apply Bayesian methods to their own work. This includes a detailed description and justification of what priors they would choose as well as what differences they would expect to see between the Bayesian and Frequentist approaches, if any, and why they would expect such differences.
Literature
The only required literature to complete the examinations are the 2 required texts and the code examples from the lectures.
Course content
The primary goal is to develop an applied and intuitive (as opposed to purely theoretical or mathematical) understanding of the topics and procedures. Whenever possible presentations will be in “Words,” “Picture,” and “Math” languages in order to appeal to a variety of learning styles. Some more advanced regression topics will be covered later in the course, but only after the introductory foundations have been established.
We will begin with a quick review of basic univariate statistics and hypothesis testing.
After that we will cover various topics in bivariate and then multiple regression, including:
• Model specification and interpretation.
• Diagnostic tests and plots.
• Analysis of residuals and outliers.
• Transformations to induce linearity.
• Interaction (“Multiplicative”) terms.
• Multicollinearity.
• Dichotomous (“Dummy”) independent variables.
• Categorical (e.g., Likert scale) independent variables.
Structure
This course will utilize approximately 525 pages of “Lecture Transcripts.” These Lecture Transcripts are organized in eleven Packets and will serve as the sole required textbook for this course. (They also will serve as an information resource after the course ends.) In addition, the Lecture Transcripts will significantly reduce the amount of notes participants have to write during class, which means they can concentrate much more on learning and understanding the material itself. These eleven Packets will be provided at the beginning of the first class.
It is important to note that this is a course on regression analysis, not on computer or software usage. While inclass examples are presented using SPSS, participants are free (and encouraged!) to use the statistical software package of their choice to replicate these examples and to analyze their own datasets. Note that many statistical software packages can be used with the material in this course. Participants can, at their option, complete several formative data analysis projects; a detailed and comprehensive “Tutorial and Answer Key” will be provided for each.
Prerequirements
This course is intended for participants who are comfortable with algebra and basic introductory statistics, and now want to learn applied ordinary least squares (OLS) multiple regression analysis for their own research and to understand the work of others.
Note: We will not use matrix algebra or calculus in this course.
Literature
The aforementioned Lecture Transcript Packets that we will use in each class serve as the de facto required textbook for this course.
In addition, the course syllabus includes full bibliographic information pertaining to several supplemental (and optional) readings for each of the nine Packets of Lecture Transcripts.
• Some of these readings are from four traditional textbooks, each of which takes a somewhat (though at times only subtly) different pedagogical approach.
• The optional supplemental readings also include several “little green books” from the Sage Series on Quantitative Applications in the Social Sciences.
• Finally, I have included several articles from a number of journals across several
academic disciplines.
Some of these optional supplemental readings are older classics and others are more recently written and published.
Examination part
A written Final Examination will be administered during the last meeting of the course.
Since this Final Examination is the only artifact that will be formally graded in the course, it will determine the course grade.
Note that class attendance, discussion participation, and studying the material outside of class are indirectly very important for earning a good score on the Final Examination.
Supplementary aids
The Final Examination will be written, openbook (i.e., class notes, Lecture Transcripts, and Tutorial and Answer Key documents are allowed), and opennote. No other materials, including laptops, cell phones, or other electronic devices, will be permitted.
The Final Exam will be two hours in length and administered during the last course meeting.
I will provide more specific “practical matter” details about this exam early in the course.
Examination content
The potential substantive content areas for the Final Examination are:
• Basic univariate statistics and hypothesis testing.
• Fundamental concepts of bivariate regression and multiple regression.
• Model specification and interpretation.
• Diagnostic tests and plots.
• Analysis of residuals and outliers.
• Transformations to induce linearity.
• Interaction (“Multiplicative”) terms.
• Multicollinearity.
• Dichotomous (“Dummy”) independent variables.
• Categorical (e.g., Likert scale) independent variables.
Literature
Literature relevant to the exam:
• Lecture Transcripts (eleven Packets; approximately 525 pages).
• Class notes (taken by each participant individually).
• Tutorial and Answer Key documents (for each optional data analysis project assignment). Supplementary/Voluntary literature not directly relevant to the exam.
• Optional supplemental readings listed in the course syllabus (and discussed earlier).
• Any other textbooks, articles, etc., the participant reads before or during the course.
Work load
At least 24 units 45 minutes each on 5 consecutive days.
Prerequisites (knowledge of topic)
This course assumes no prior experience with machine learning or R, though it may be helpful to be familiar with introductory statistics and programming.
Hardware
A laptop computer is required to complete the inclass exercises.
Software
R (https://www.rproject.org/) and R Studio (https://www.rstudio.com/products/rstudio/) are available at no cost and are needed for this course.
Learning objectives
Students will leave with an understanding of the foundational machine learning methods as well as the ability to apply machine learning to their own field of work or study using the R programming language.
Course content
Machine learning, put simply, involves teaching computers to learn from experience, typically for the purpose of identifying or responding to patterns or making predictions about what may happen in the future. This course is intended to be an introduction to machine learning methods through the exploration of realworld examples. We will cover the basic math and statistical theory needed to understand and apply many of the most common machine learning techniques, but no advanced math or programming skills are required. The target audience may include social scientists or practitioners who are interested in understanding more about these methods and their applications. Students with extensive programming or statistics experience may be better served by a more theoretical course on these methods.
Structure
The course will be designed to be interactive, with ample time for handson practice with the Machine Learning methods. Each day will include several lectures based on a Machine Learning topic, in addition to handson “lab” sections to apply the learnings to new datasets (or your own data, if desired).
The approximate schedule will be as follows:
Day 1: Introducing Machine Learning with R
 How machines learn
 Using R and R Studio
 Data exploration
 kNearest Neighbors
 Lab sections – installing R, choosing and exploring own dataset (if desired)
Day 2: Intermediate ML Methods – Classification Models
 Quiz on Day 1 material
 Naïve Bayes
 Lab sections – practicing with kNN and Naïve Bayes
Day 3: Intermediate ML Methods – Numeric Prediction
 Quiz on Day 2 material
 Decision Trees and Rule Learners

 Logistic regression
 Lab sections – practicing with classification and regression methods
Day 4: Advanced Classification Models
 Quiz on Day 3 material
 Neural Networks
 Support Vector Machines
 Random Forests
 Lab section – practice with neural networks, SVMs, and random forests
Day 5: Other ML Methods
 Quiz on Day 4 material
 Association Rules
 Hierarchical clustering
 KMeans clustering
 Model evaluation
 Lab section – practice with these methods, work on final report
Literature
Mandatory
Machine Learning with R (4th ed.) by Brett Lantz (2023). Packt Publishing
Supplementary / voluntary
None required.
Mandatory readings before course start
Please install R and R Studio on your laptop prior to the 1st class. Be sure that these are working correctly and that external packages can be installed. Instructions for doing this are in the first chapter of Machine Learning with R.
Examination part
100% of the course grade will be based on a project and final report (approximately 10 pages), to be delivered within 23 weeks after the course. The project is intended to demonstrate your ability to apply the course materials to a dataset of your own choosing. Students should feel free to use a project related to their career or field of study. For example, it is possible to use this opportunity to advance dissertation research or complete a task for one’s job. The exact scoring criteria for this assignment will be provided on the first day of class. This will be graded based on its use of the methods covered in class as well as making appropriate conclusions from the data.
There will also be brief quizzes at the start of each lecture, which cover the previous day’s materials. These are ungraded and are designed to provoke thought and discussion.
Supplementary aids
Students may reference literature and class materials as needed when writing the final project report.
Examination content
The final project report should illustrate an ability to apply machine learning methods to a new dataset, which may be on a topic of the student’s choosing. The student should explore the data and explain the methods applied. Detailed instructions will be provided on the first day of class.
Examination relevant literature
The written report is only expected to reflect knowledge of the material presented in class, which covers chapters 1 to 10 in the Machine Learning with R (4th ed.) textbook noted above.
Prerequisites (knowledge of topic)
This course is a continuation of Introductory Machine Learning with R and assumes a basic knowledge of at least several machine learning classification methods. Students having equivalent realworld experience (via other ML courses or onthejob experiences) are also welcome.
Hardware
A laptop computer is required to complete the inclass exercises.
Software
R (https://www.rproject.org/) and R Studio (https://www.rstudio.com/products/rstudio/) are available and no cost and are needed for this course.
Learning objectives
Students will develop the ability to build more advanced machine learning skills by practicing on a large and challenging dataset, applying advanced data preparation, model tuning, and evaluation strategies, as well as learning about how “big data” techniques can improve even conventional ML models.
Course content
With machine learning, it is often difficult to make the leap from classroom examples to the realworld. Realworld applications often present challenges that require more advanced approaches for preparing, exploring, modeling, and evaluating the data. The goal of this course is to prepare students to independently apply machine learning methods to their own tasks. We will cover the practical techniques that are not often found in textbooks but discovered through handson experience. We will practice these techniques by simulating a machine learning competition like those found on Kaggle (https://www.kaggle.com/). The target audience includes students who are interested in applying ML knowledge to more difficult problems and learning more advanced techniques to improve the performance of traditional ML methods.
Structure
The course will be designed to be interactive, with ample time for handson practice. Each day will include at least one lecture based on the day’s topic in addition to a handson “lab” section to apply the learnings to a competition dataset (or one’s own data).
The tentative schedule is as follows:
Day 1: Being Successful with Machine Learning
 What makes a successful ML model?
 ML models in the real world
 Learning to explore data
 Putting the “science” in data science
 Advanced model evaluation
Day 2: Advanced data preparation
 Why is 80% of a modeling project spent on data preparation?
 Feature engineering strategies
 The R data pipeline – tidyverse
Day 3: Challenging data: Too much, too little, too complex
 The challenges of high dimensional and sparse data
 Handling missing data (missing data imputation)
 The problem of imbalanced data (SMOTE algorithm)
Day 4: Building Better Learners
 Tuning stock models for better performance
 Improving model performance with ensembles (Random Forest, XGBoost)
 Stacking models for metalearning
Day 5: Making Use of Big Data
 Practical applications of deep learning

Literature
Mandatory
This course covers Chapter 1115 in Machine Learning with R (4th ed.) by Brett Lantz (2023). Packt Publishing. A small number of additional readings will be distributed in PDF format prior to the start of each class day.
Supplementary / voluntary
None required.
Mandatory readings before course start
Students should have R and R Studio installed on their laptop prior to the 1st class. Be sure that these are working correctly and that external packages can be installed. Instructions for doing this are in the first chapter of Machine Learning with R.
Examination part
80% of the course grade will be based on a project and final report (approximately 510 pages), to be delivered within 23 weeks after the course in R Notebook format. The project is based on a challenging realworld dataset given to all course participants. The project will be graded based on its use of the methods covered in class as well as making appropriate conclusions from the data.
The remaining 20% of the course grade will be based on participation during inclass discussions and performance during the machine learning competitions. The ML competition winner(s) will receive maximum points, while runnersup will receive a fraction of the points based on effort, innovation, and proximity to the winners’ performance. The performance metrics for this competition will be provided prior to the competition.
Supplementary aids
Students may reference any literature as needed when writing the final report.
Examination content
The primary goal of the final project is for students to gain an ability to solve difficult ML tasks. The project should reflect an understanding of the material covered throughout the week, as well as an ability to apply the material in new and innovative ways.
Examination relevant literature
The written report is only expected to reflect knowledge of the material presented in class, which covers chapters 11 to 15 in the Machine Learning with R (4th ed.) textbook noted above.
Course content
The goal is to develop an applied and intuitive (not purely theoretical or mathematical) understanding of the topics and procedures, so that participants can use them in their own research and also understand the work of others. Whenever possible presentations will be in “Words,” “Picture,” and “Math” languages in order to appeal to a variety of learning styles.
Advanced regression topics will be covered only after the foundations have been established. The ordinary least squares multiple regression topics that will be covered include:
 Various F‑tests (e.g., group significance test; Chow test; relative importance of
variables and groups of variables; comparison of overall model performance).  Categorical independent variables (e.g., new tests for “Intervalness” and
“Collapsing”).  Dichotomous dependent variables: Logit and Probit analysis.
 Outliers, influence, and leverage.
 Advanced diagnostic plots and graphical techniques.
 Matrix algebra: A quick primer. (Optional)
 Regression models… now from a matrix perspective.
 Heteroskedasticity: Definition, consequences, detection, and correction.
 Autocorrelation: Definition, consequences, detection, and correction.
 Generalized Least Squares (GLS) and Weighted Least Squares (WLS).
Structure
This course will utilize approximately 325 pages of “Lecture Transcripts.” These Lecture Transcripts are organized in nine Packets and will serve as the sole required textbook for this course. (They also will serve as an information resource after the course ends.) In addition, the Lecture Transcripts will significantly reduce the amount of notes participants have to write during class, which means they can concentrate much more on learning and understanding the material itself. These nine Packets will be provided at the beginning of the first class.
It is important to note that this is a course on regression analysis, not on computer or software usage. While in‑class examples are presented using SPSS, participants are free and encouraged to use the statistical software package of their choice to replicate these examples and to analyze their own datasets. Note that many statistical software packages can be used with the material in this course. Participants can, at their option, complete several formative data analysis projects; a detailed and comprehensive “Tutorial and Answer Key” will be provided for each.
Prerequisites
This course is a continuation of Tim McDaniel’s “Regression I – Introduction” course. While it is not necessary that participants have taken that specific course, they will need to be familiar with many of the topics that are covered in it.
Note: We will use matrix algebra in the second half of the course. We will not use calculus.
Literature
The aforementioned Lecture Transcript Packets that we will use in each class serve as the de facto required textbook for this course.
In addition, the course syllabus includes full bibliographic information pertaining to several supplemental (and optional) readings for each of the nine Packets of Lecture Transcripts.
 Some of these readings are from four traditional textbooks, each of which takes a somewhat (though at times only subtly) different pedagogical approach.
 The optional supplemental readings also include several “little green books” from the Sage Series on Quantitative Applications in the Social Sciences.
 Finally, I have included several articles from a number of journals across several academic disciplines.Some of these optional supplemental readings are older classics and others are more recently written and published.
Examination part
Decentral ‑ Written examination (100%)
Supplementary aids
Open Book
Examination content
The potential substantive content areas for the Final Examination are:
 Various F‑tests (e.g., group significance test; Chow test; relative importance of
variables and groups of variables; comparison of overall model performance).  Categorical independent variables (e.g., new tests for “Intervalness” and “Collapsing”).
 Dichotomous dependent variables: Logit and Probit analysis.
 Outliers, influence, and leverage.
 Advanced diagnostic plots and graphical techniques.
 Regression models… now from a matrix perspective.
 Heteroskedasticity: Definition, consequences, detection, and correction.
 Autocorrelation: Definition, consequences, detection, and correction.
 Generalized Least Squares (GLS) and Weighted Least Squares (WLS).
Since this final examination is the only artifact that will be formally graded in the course, it will determine the course grade. Note that class attendance, discussion participation, and studying the material outside of class are indirectly very important for earning a good score on the final examination.
The final examination will be written, open‑ook (i.e., class notes, Lecture Transcripts, and Tutorial and Answer Key documents are allowed), and open‑note. No other materials, including Laptops, cell phones, or other electronic devices, will be permitted.The written final exam will be two hours in length and administered during the last course meeting.
Literature
Literature relevant to the exam:
 Lecture Transcripts (nine Packets; approximately 325 pages).
 Class notes (taken by each participant individually).
 Assignment Tutorial and Answer Key documents (for each optional data analysis
project).
Supplementary/Voluntary literature not directly relevant to the exam:
 Optional supplemental readings listed in the course syllabus (and discussed earlier).
 Any other textbooks, articles, etc., the participant reads before or during the course.
Prerequisites (knowledge of topic)
Comfortable familiarity with univariate differential and integral calculus, basic probability theory, and linear algebra is required. Students should have completed Ph.D.level courses in introductory statistics, and in linear and generalized linear regression models (including logistic regression, etc.), up to the level of Regression III. Familiarity with discrete and continuous univariate probability distributions will be helpful.
Hardware
Students will be required to provide their own laptop computers.
Software
All analyses will be conducted using the R statistical software. R is free, opensource, and runs on all contemporary operating systems. The instructor will also offer support for students wishing to use Stata.
Learning objectives
Students will learn how to visualize, analyze, and conduct diagnostics on models for observational data that has both crosssectional and temporal variation.
Course content
Analysts increasingly find themselves presented with data that vary both over crosssectional units and across time. Such panel data provides unique and valuable opportunities to address substantive questions in the economic, social, and behavioral sciences. This course will begin with a discussion of the relevant dimensions of variation in such data, and discuss some of the challenges and opportunities that such data provide. It will then progress to linear models for oneway unit effects (fixed, between, and random), models for complex panel error structures, dynamic panel models, nonlinear models for discrete dependent variables, and models that leverage panel data to make causal inferences in observational contexts. Students will learn the statistical theory behind the various models, details about estimation and inference, and techniques for the visualization and substantive interpretation of their statistical results. Students will also develop statistical software skills for fitting and interpreting the models in question, and will use the models in both simulated and real data applications. Students will leave the course with a thorough understanding of both the theoretical and practical aspects of conducting analyses of panel data.

Examination part
Students will be evaluated on two written homework assignments that will be completed during the course (20% each) and a final examination (60%). Homework assignments will typically involve a combination of simulationbased exercises and “real data” analyses, and will be completed during the evenings while the class is in session. For the final examination, students will have two alternatives:
• “InClass”: Complete the final examination in the afternoon of the last day of class (from roughly noon until 6:00 p.m. local time), or
• “TakeHome”: Complete the final examination during the week following the end of the course (due date: TBA).
Additional details about the final examination will be discussed in the morning session on the first day of the course.
Supplementary aids
The exam will be a “practical examination” (see below for content). Students will be allowed access to (and encouraged to reference) all course materials, notes, help files, and other documentation in completing their exam.
Examination content
The examination will involve the application of the techniques taught in the class to one or more “live” data example(s). These will typically take the form of either (a) a replication and extension of an existing published work, or (b) an original analysis of observational data with a panel / timeseries crosssectional component. Students will be required to specify, estimate, and interpret various statistical models, to conduct and present diagnostics and robustness checks, and to give detailed justifications for their choices.
Examination relevant literature
See above. Details of the examination literature will be finalized prior to the start of class.
Content
Statistical mediation and moderation analyses are among the most widely used data analysis techniques in social science, health, and business fields. Mediation analysis is used to test hypotheses about various intervening mechanisms by which causal effects operate. Moderation analysis is used to examine and explore questions about the contingencies or conditions of an effect, also called “interaction”. Increasingly, moderation and mediation are being integrated analytically in the form of what has become known as “conditional process analysis,” used when the goal is to understand the contingencies or conditions under which mechanisms operate. An understanding of the fundamentals of mediation and moderation analysis is in the job description of almost any empirical scholar. In this course, you will learn about the underlying principles and the practical applications of these methods using ordinary least squares (OLS) regression analysis and the PROCESS macro for SPSS, SAS and R invented by the course instructor.
Topics covered in this fiveday course include:
 Path analysis: Direct, indirect, and total effects in mediation models.
 Estimation and inference about indirect effects in single mediator models.
 Models with multiple mediators
 Mediation analysis in the twocondition withinsubject design.
 Estimation of moderation and conditional effects.
 Probing and visualizing interactions.
 Conditional Process Analysis (also known as “moderated mediation”)
 Quantification of and inference about conditional indirect effects.
 Testing a moderated mediation hypothesis and comparing conditional indirect effects
As an introductorylevel course, we focus primarily on research designs that are experimental or crosssectional in nature with continuous outcomes. We do not cover complex models involving dichotomous outcomes, latent variables, models with more than two repeated measures, nested data (i.e., multilevel models), or the use of structural equation modeling.
This course will be helpful for researchers in any field—including psychology, sociology, education, business, human development, political science, public health, communication—and others who want to learn how to apply the latest methods in moderation and mediation analysis using readilyavailable software packages such as SPSS, SAS and R.
Prerequisites (knowledge of topic)
Participants should have a basic working knowledge of the principles and practice of multiple regression and elementary statistical inference. No knowledge of matrix algebra is required or assumed, nor is matrix algebra ever used in the course.
Hardware and Software
Computer applications will focus on the use of OLS regression and the PROCESS macro for SPSS, SAS and R developed by the instructor that makes the analyses described in this class much easier than they otherwise would be.
Because this is a handson course, participants are strongly encouraged to bring their own laptops (Mac or Windows) with a recent version of SPSS Statistics (version 23 or later), SAS (release 9.2 or later), or R (version 3.6 or later) installed. (Only one statistical package is required, but participants can use more than one if desired) SPSS users should ensure their installed copy is patched to its latest release. SAS users should ensure that the IML product is part of the installation. You should have good familiarity with the basics of ordinary least squares regression, as well as the use of SPSS, SAS, or R. You are also encouraged to bring your own data to apply what you’ve learned.
STATA users can benefit from the course content, but PROCESS makes these analyses much easier and is not available for STATA.
Literature
This course is a companion to the second edition of the instructor’s book Introduction to Mediation, Moderation, and Conditional Process Analysis, published by The Guilford Press. The content of the course overlaps the book to some extent, but many of the examples are different, and this course includes some material not in the book. A copy of the book is not required to benefit from the course, but it could be helpful to reinforce understanding.
Examination
100% of assessment will be based on a written final examination at the end of the course. The exam will be a combination of multiple choice questions and shortanswer/fill in the blank questions, along with some interpretation of computer output. Students will take the examination home on the last day of class and return it to the instructor within one week.
During the examination students will be allowed to use all course materials, such as PDFs of PowerPoint slides, student notes taken during class, and any other materials distributed or studentgenerated during class. Although the book mentioned in “Literature” is not a requirement of the course nor is it necessary to complete the exam, students may use the book if desired during the exam.
A computer is not required during the exam, though students may use a computer if desired, for example as a storage and display device for class notes provided to them during class.
Among the topics of the exam may include how to quantify and interpret path analysis models, calculate direct, indirect, and total effects, and determine whether evidence of a mediation effect exists in a data set based on computer output provided or other information. Also covered will be the testing moderation of an effect, interpreting evidence of interaction, and probing interactions. Students will be asked to generate or interpret conditional indirect effects from computer output given to them and/or determine whether an indirect effect is moderated. Students may be asked to construct computer commands that will conduct certain analyses. All questions will come from the content listed in “Course Content” above.
Prerequisites (knowledge of topic)
 Proficiency in basic programming, with Python highly recommended.
 Understanding of linear algebra, analysis, and statistics at the undergraduate level.
Hardware
 Personal laptop with Mac OSX or Linux, Windows.
 Tablets (iOS, Windows) will not be working with this course.
 Laptop adapter for connecting to the Swiss electricity grid.
Software
 Webbrowser (Chrome, Safari, Firefox)
 Jupyter, Binder, or Google CoLab notebook.
 Local Python installation including Numpy, Scipy, scikitlearn, PyTorch
Learning objectives

Prerequisites (knowledge of topic)
There is no prerequisite knowledge. However, some familiarity with experimental design (e.g., through the GSERM course “Experimental Methods for Behavioral Science”) is very useful, as the course delves deep into practical aspects of conducting experimental research online.
Hardware
Students will complete course work on their own laptop computers.
Software
The course will rely on several online research tools, including Amazon Mechanical Turk, Prolific, CloudResearch, Qualtrics, and more. Accounts are typically free to open (at least in trial version), though some might require depositing a credit card number.
Learning objectives
– conducting online “lab” surveys and experiments on several alternative platforms
– using advanced features to conduct richer and innovative “lab” studies
– conducting “field” studies on social media platforms, search engines, and beyond
– improving research designs by scraping web data
– making online research more publishable, reproducible, and replicable
Course content
The Internet is revolutionizing how empirical research is conducted across the social sciences. Without the need for intermediaries, individual researchers can now conduct largescale experiments on human participants, longitudinal surveys of rare populations, A/B tests on social media, and more. In this course, you will learn how to harness these opportunities while avoiding the many pitfalls of online research. The course is tailored for researchers in psychology, economics, business, and any other area of academia or industry who investigate human behavior.
We will cover the nuts and bolts of conducting “lab” experiments on alternative Internet platforms, including techniques to maximize the validity and reproducibility of research findings. We will also discuss how to unlock the potential of the Internet for more elaborate, richer designs (e.g., longitudinal, interactive) that go beyond simple survey experiments. Additionally, we will teach you how to scrape publicly available information and to conduct “field” experiments on social media, gathering realworld, immediately applicable insights about consumers, workers, and Internet users more generally. Importantly, technical and practical insights will explicitly serve the goal to improve the rigor and the publishability of participants’ own research. To this end, we will include discussions on whether and how to combine online and offline investigations, how to preregister and report online research in a paper, and more.
The course relies on a mix of discussions, demonstrations, and exercises that use participants’ own research needs and projects as starting points. At the end of the week, participants will be fully equipped to design, execute, and report valid online research for their own investigations.
Structure
Each class day includes lecturing, applications, and discussions.

Examination relevant literature
Lecture slides and notes.
Prerequisites (knowledge of topic)
Basic knowledge of descriptive statistics, data analysis and R is useful, but not necessary. Participants need to bring their own laptop and complete our detailed installation instructions for R and RStudio (both open source software) shared prior to the course.
Learning objectives
The creation and communication of data visualizations is a critical step in any data analytic project. Modern opensource software packages offer ever more powerful data visualizations tools. When applied with psychological and design principles in mind, users competent in these tools can produce data visualizations that easily tell more than a thousand words. In this course, participants learn how to employ stateoftheart data visualization tools within the programming language R to create stunning, publicationready data visualizations that communicate critical insights about data. Prior to, during, and after the course participants work their own data visualization project.
Course content
Each day will contain a series of short lectures and demonstrations that introduce and discuss new topics. The bulk of each day will be dedicated to handson, stepbystep exercises to help participants ‘learn by doing’. In these exercises, participants will learn how to readin and prepare data, how to create various types of static and interactive data visualizations, how to tweak them to exactly fit one’s needs, and how to embed them in digital reports. Accompanying the course, each participant will work on his or her own data visualization project turning an initial visualization sketch into a onepage academic paper featuring a polished, welldesigned figure. To advance these projects, participants will be able to draw on support from the instructors in the afternoons of course days two to four.

Prerequisites (knowledge of topic)
Students should have previous exposure to social research methods, including basic training in quantitative methods, at the postbaccalaureate level.
Hardware
Laptop (PC or Mac): Students should bring a laptop. The course will include instruction in the use of the software package fsQCA (for both Windows and Mac). I strongly recommend running the fsQCA software package in its Windows version, either on a Windows machine, using a Windows virtual machine on a Mac, or using the GSERM virtual machine. The fsQCA Mac version tends to be much less stable.
Software
Please install the fsQCA software package ahead of the course or ensure you can run it in a virtual environment. If you install it on your machine it can be downloaded for free at fsqca.com
Learning objectives
Qualitative comparative analysis (QCA) is a research approach consisting of both an analytical technique and a conceptual perspective for researchers interested in studying configurational phenomena. QCA is particularly appropriate for the analysis of causally complex phenomena marked by multiple, conjunctural causation where multiple causes combine to bring about outcomes in complex ways.
QCA was developed in the 1980s by Charles Ragin, a sociologist and political scientist, as an alternative comparative approach that lies midway between the primarily qualitative, caseoriented approach and the primarily quantitative, variableoriented approach, with the goal of bridging both by combining their advantages and tackling situations where causality is complex and conjunctural. QCA uses Boolean algebra for the analysis of set relations and allows researchers to formally analyze patterns of necessity and sufficiency regarding outcomes of interest. Since its inception, QCA has developed into a broad set of techniques that share their setanalytic nature and include both descriptive and inferential techniques.
Many researchers have drawn on QCA because it offers a means to systematically analyze data sets with relatively few observations. In fact, QCA was originally developed for small to mediumN situations with between 10 and 50 cases. In such situations there are frequently too many cases to pursue a classical qualitative approach but too few cases for conventional statistical analysis. However, more recently, researchers have also applied QCA to medium and largeN situations marked by hundreds of thousands of cases. While these applications require some changes to how QCA is applied, they retain many advantages for analyzing situations that are configurational in nature and marked by causal complexity.
The goal of this workshop is to provide a groundup introduction to Qualitative Comparative Analysis (QCA) and fuzzy sets. Participants will get intensive instruction in the method as well as handson experience with the fsQCA software package. On completion of the course, participants should be prepared to design and execute research projects using the setanalytic approach.
Specifically, after successful completion of you should be able to:
 understand the goals, assumptions, and key concepts of QCA
 conduct data analysis using the fsQCA software package
 design and execute research projects using a setanalytic approach
 apply advanced forms of setanalytic investigation
I would like this workshop to be as useful to you as possible. To get the most out of this workshop, you would ideally already be working on an empirical project that might be aided by taking a configurational approach, but that is not essential. Over the course of this workshop, I hope you will be thinking about how you can apply these methods to your research, and I will do my best to be of assistance.

Unit 1. Introduction to the Comparative Method
The goal of this first unit is to offer an introduction to the logic of comparative research, as this perspective will be fundamental in informing our thinking for the coming days. The focus is on understanding social research from a setanalytic perspective as well as examining the distinctive place of configurational and comparative research.
Key Readings:
Ragin, 2008 (“Redesigning Social Inquiry”): Chapters 12
Unit 2. The Basics of QCA
We’ll move on to the basics of QCA. We will begin with an Introduction to Boolean algebra and setanalytic methods. Other issues we will cover include setanalytic analysis vs. correlational analysis, the concepts of necessity and sufficiency as well as consistency, coverage, and set coincidence. Time permitting, we will also examine caseoriented research strategies for theory building.
Key Readings:
Ragin, 2000: Chapters 35
Ragin, 2008: Chapters 13
Unit 3. Crisp Set Analysis
In this unit, we will dive into crispset QCA (csQCA), the simpler version of QCA using binary data sets. This will include the coding of data, the construction of truth tables, and understanding the three solutions—complex, parsimonious, and intermediate. We will also begin to examine the importance of counterfactual analysis based on easy versus difficult counterfactuals. Topics also include understanding consistency and coverage in crispset truth table analysis.
Key Readings:
Ragin, 2000: Chapters 35
Unit 4. Fuzzy Set Analysis I
Fuzzy set analysis presents a slightly more complex version of QCA. We will start with the notions of fuzzy sets and fuzzy set relations before moving on to calibrating fuzzy sets and fuzzy set consistency, coverage, and coincidence.
Ragin, 2008: Chapters 45
Unit 5. The FuzzySet Truth Table Algorithm
We will next cover the fuzzyset truth table algorithm. Building on crisp set analysis, we will further examine issues around limited diversity, fuzzy sets and counterfactual analysis. We also will work with sample data sets.
Unit 6. Advanced Topics in QCA
This unit provides us with an opportunity to catch up and delve deeper into some of the topics introduced above. Should we feel comfortable enough, we will move on to some more advanced topics in QCA, including the testing of causal recipes and substitutable causal conditions.
Key Readings:
Ragin, 2008: Chapters 710
Unit 7. LargeN Applications of QCA
The last unit will provide examples of recent largeN applications of QCA. These examples will give us an opportunity to raise further questions about how to execute research using a setanalytic approach. We will also reserve some time for further questions that have come up during the workshop.

Course content
This course builds directly upon the foundations laid in Regression II, with a focus on successfully applying linear and generalized linear regression models. After a brief review of the linear regression model, the course addresses a series of practical issues in the application of such models: presentation and discussion of results (including tabular, graphical, and textual modes of presentation); fitting, presentation, and interpretation of two and threeway multiplicative interaction terms; model specification for dealing with nonlinearities in covariate effects; and postestimation diagnostics, including specification and sensitivity testing. The course then moves to a discussion of generalized linear models, including logistic, probit, and Poisson regression, as well as textual, tabular, and graphical methods for presentation and discussion of such models. The course concludes with a “participants’ choice” session, where we will discuss specific issues and concerns raised by students’ own research projects and agendas.

Hardware
Laptop.
Software
None.
Learning objectives
Upon completing the course, students will be equipped with a concrete set of Bayesianinspired best practices to deploy in their own research, as well as widelyapplicable analytic skills that will help them to better evaluate and critique sociopolitical analysis.
Course content
The way we intuitively approach qualitative case research is similar to how we read detective novels. We consider various different hypotheses to explain what occurred— whether a major tax reform in Chile, or the death of Samuel Ratchett on the Orient Express—drawing on the literature we have read (e.g. theories of policy change, or other Agatha Christie mysteries) and any salient previous experiences we have had. As we gather evidence and discover new clues, we update our beliefs about which hypothesis provides the best explanation—or we may introduce a new alternative that occurs to us along the way. Bayesianism provides a natural framework that is both logically rigorous and grounded in common sense, that governs how we should revise our degree of belief in the truth of a hypothesis—e.g., “the imperative of attracting globallymobile capital motivated policymakers to reform the tax system,” or “a lone gangster sneaked onboard the train and killed Ratchett as revenge for being swindled”—given our relevant prior knowledge and new information that we learn during our investigation. Bayesianism is enjoying a revival across many fields, and it offers a powerful tool for improving inference and analytic transparency in qualitative casestudy research.
This interactive course introduces the principles of Bayesian reasoning, with applications to processtracing, comparative case studies, and multimethod research. Participants will learn how to construct wellarticulated rival hypotheses to compare, systematically assess the inferential weight of qualitative evidence, avoid common cognitive biases that can lead to sloppy reasoning, and evaluate which hypothesis provides the best explanation through Bayesian updating. The course will also address key aspects of research design, including case selection. We will further explore the potential for Bayesianism to serve as a bridge between quantitative and qualitative research. Throughout, we will conduct a wide range of exercises and group work to give participants handson practice applying Bayesian techniques. Upon completing the course, participants will be able to read case studies more critically, evaluate whether and to what extent the evidence presented supports the authors’ conclusions, and apply Bayesian principles in their own research.
Structure
Day 1. Introduction to Bayesian reasoning
Session A: Preview of best practices and foundations of Bayesian probability
Session B: Constructing rival hypotheses and evaluating prior odds
Because we live in a world of uncertainty, we intuitively reason in terms of probabilities. For example, we think about how likely it is to rain in the afternoon, given the weather conditions we observe in the morning. If it does rain in the afternoon, we adjust our expectations about the likelihood of rain tomorrow. But even though probabilistic thinking is common in daily life, we don’t always reason correctly about probabilities, especially when we’re making quick judgements. Our first session will begin with an introduction to the fundamentals of Bayesian probability. We will come up to speed on conditional probability and Bayes’ rule, with some fun practice problems along the way. In the second session, we will go on to talk about how to construct wellarticulated rival hypotheses to compare, and how to assign prior odds, which express our initial view about which hypothesis is more plausible given the background knowledge that we bring to our research.
Day 2. Assessing evidentiary import
Session A: Likelihood ratios
Session B: Silver Blaze exercise
We now turn to identifying evidence, which includes any salient observation about the world that helps us adjudicate between rival hypotheses, and evaluating likelihood ratios, which is how we figure out how strongly the evidence supports a hypothesis over rivals. Evaluating likelihood ratios is the key step in Bayesian analysis that tells us how to update our prior odds. Here we must ask which hypothesis makes the evidence more expected. The key is to “mentally inhabit the world” of each hypothesis. We need to think about the most plausible scenario that would lead us to observe the evidence in the world of a particular hypothesis, and then ask whether that story would be more or less plausible than the most sensible scenario we can envision in the world of the alternative hypothesis. We will consider concrete examples from research on international investment treaties signed by South Africa (Poulsen 2015, CUP) and research on social spending in Mexico (Garay 2016, CUP), along with an exercise using clues from the famous Sherlock Holmes story Silver Blaze.
Day 3. Logodds updating
Session A: Weight of evidence; State building exercise
Session B: Market reform exercise
We will now introduce the logodds form of Bayes’ rule and the weight of evidence, which is closely related to the likelihood ratio. This approach greatly simplifies Bayesian analysis, and it allows us to quantify probabilities in order to better communicate our views and aggregate the probative value of multiple pieces of evidence more systematically. We will practice this approach with group exercises that examine case studies on statebuilding and market reform.
Day 4. Bayesian reasoning for comparative case studies
Session A: Multiple hypotheses and multiple cases
Session B: Case selection and research design
Our next step is to apply Bayesian reasoning in situations where we wish to compare more than just two rival hypotheses, and in research that involves studying more than a single case. When working with multiple rival hypotheses, we simply carry out a set of pairwise comparisons. When working with multiple cases, weights of evidence aggregate across the cases in the same way that weights of evidence add up for multiple clues pertaining to a single case. The second session will introduce an informationtheoretic approach to case selection, where the goal is to choose cases that will be highly informative for developing theory and/or for comparing rival hypotheses. We will discuss a number of practical guidelines for case selection that emerge from this approach. If time allows, we will also discuss guidelines for how to proceed when evidence we discover inspires us to devise a new hypothesis.
Day 5. Bayesian reasoning in methodological perspective
Session A: Contrasting Bayesianism with alternative approaches to qualitative research
Session B: Applying Bayesian reasoning across multiple types of evidence
We will conclude by highlighting the relative advantages of Bayesianism and how it differs from frequentist statistical inference, as well as other methodologies for process tracing and qualitative research, with some fun exercises along the way. We will further discuss how Bayesianism can be applied across very different kinds of evidence with an application to the question of SARSCoV2 origins.

Prerequisites (knowledge of topic)
Basic methodological knowledge of the scientific method and experimental social research is beneficial but not necessary. Ideally you will bring a project idea to the course we can use for a preregistration. This could be a study you plan to work on or a research project you are already in the middle of. This means you have a rough idea of what you want to do, the measures you want to use and a concrete research question.
Hardware
Bring your own device (ideally a laptop) so you can code along and work on your own materials as we go.
Software
Browser / Texteditor / RStudio (installation instructions will be provided, can also be used in a cloud version via Browser)
Learning objectives
Upon completion of the course, participants will be able to:
 Discuss the incentive structure of modern academic environments against the
backdrop of research history  Explain the importance of transparency and openness for the scientific
method.  Discuss the benefits and challenges of sharing research materials openly.
 Preregister their own empirical work.
 Make own research data and code openly available.
 Collaborate with peers on GitHub to cowrite code and create reproducible projects in RStudio.
Course content
The course addresses central aspects of good research practice and invites you to think
about your own methods and academic habits. We discuss what qualifies as “good”
research practice, mirroring current debates in various disciplines. The course is
intended to shed light on these multifaceted and stimulating debates and to
familiarize participants with questions such as: Why is transparency and openness
needed in research? What does “open” mean for different perspectives on knowledge
generation (i.e., different disciplines, methods, etc.)? Why do we publish knowledge
and findings at all, and how can such publications be made more accessible? Which
other aspects of the research and teaching process can be designed “better” in
accordance with the principles of good research practice? What are limits of
openness in research?
With these questions comes the need for using certain tools to achieve transparency
and openness. Collaborative work on Github for writing code and producing
reproducible projects in RStudio will be introduce. We will also explore the ideas
connected to preregistration of your hypothesis and analysis plan on the open
science framework (osf.io).
The course takes place from 9am to 3pm on five consecutive course days. Each day will
contain a series of short lectures and demonstrations that introduce and discuss new
topics. Handson exercises will give you as much practical experience as possible in
applying the new ideas introduced during the week.

Prerequisites (knowledge of topic)
 A graduate statistics course at an introductory level,
 Some knowledge of regression analysis is recommendable and desirable, but not expected from the participants.
Hardware
Your own laptop with R installed on it.
Software
R.
Learning objectives
 To become familiar with the basics as well as some intermediate to advanced empirically and theoretically relevant topics of multilevel and longitudinal modeling;
 To acquire a nuanced understanding and skills for assessing the need for multilevel modeling of data from an empirical study;
To be able at the end of the course to carry out multilevel and longitudinal modeling with R, including multilevel model selection (model comparison/model choice).  To be in a position to interpret statistically and substantively the results from a multilevel and/or longitudinal modeling session with R;
 To be in a position to report the findings from such analyses in a publishable document.
Course content
This intermediate level 5day course presents the highly popular methodology of multilevel modeling (MLM) across the social, marketing, business, behavioral, educational, organizational, life, and biomedical sciences. In addition, it discusses its specific applications in the analysis of longitudinal data that are currently very frequently collected in these and cognate disciplines.
MLM provides a widely applicable approach to modeling and accounting for clustering effects that impact the majority of contemporary empirical studies in these sciences. A key feature of these effects is the associated relationship among and similarity of the observed scores collected from members of studied groups or clusters of units of analysis (usually persons, respondents, patients, employees, students, clients, etc., but could also be higherorder aggregates of them). If this similarity (withingroup ‘correlation’) is not properly handled, as would be the case when using standard statistical analysis methods, incorrect statistical results ensue, followed by substantive conclusions that can be seriously misleading. A key achievement of MLM is the proper handling of the clustering effects, yielding valid and dependable statistical and substantive results.
A particular field of application of MLM is that of longitudinal data analysis and modeling. Designs and studies producing such data are very frequently utilized in the social, marketing, business, behavioral, educational, medical, organizational, and life as well as related sciences. Through appropriate use of MLM, whose detailed coverage is also part of this course, data resulting from such studies involving repeated measures can be analyzed and modeled applying relevant statistical procedures that lead to valid and dependable results entailing correct and trustworthy substantive conclusions.

Prerequisites (knowledge of topic)
Participants should have a basic working knowledge of the principles and practice of multiple regression and elementary statistical inference. Because this is a second course, participants should either be familiar with the contents of the first edition of Introduction to Mediation, Moderation, and Conditional Process Analysis and the statistical procedures discussed therein or should have taken the first course through GSERM or elsewhere. Participants should also have experience using syntax in SPSS, SAS, or R, and it is assumed that participants will already have some experience using the PROCESS macro. No knowledge of matrix algebra is required or assumed, nor is matrix algebra ever used in the course.
Hardware
Students are strongly encouraged to bring their own laptops (Mac or Windows)
Software
Laptops need a recent version of SPSS Statistics (version 19 or later), SAS (release 9.2 or later) or R (3.6 or later) installed. SPSS users should ensure their installed copy is patched to its latest release. SAS users should ensure that the IML product is part of the installation. STATA users can benefit from the course content, but PROCESS makes these analyses much easier and is not available for STATA.
Learning objectives
 Apply and report on tests of moderated mediation using the index of moderated mediation
 Identify models for which partial and conditional moderated mediation are appropriate.
 Apply and report mediation analysis with multicategorical independent variables.
 Test and probe an interaction involving a multicategorical independent variable or moderator.
 Apply and report tests of moderated mediation involving a multicategorical independent variable.
 Generalize the index of moderated mediation to models with serial mediation
 Estimate and conduct inference in mediation, moderation, and moderated mediation contexts for twoinstance repeatedmeasures designs.
 Generate and specify custom models in PROCESS
Course content
Statistical mediation and moderation analyses are among the most widely used data analysis techniques. Mediation analysis is used to test various intervening mechanisms by which causal effects operate. Moderation analysis is used to examine and explore questions about the contingencies or conditions of an effect, also called ʺinteraction.ʺ Conditional process analysis is the integration of mediation and moderation analysis and used when one seeks to understand the conditional nature of processes
(i.e., ʺmoderated mediationʺ).
In Introduction to Mediation, Moderation, and Conditional Process Analysis: A Regression‑Based Approach (www.guilford.com/p/hayes3) Dr. Andrew Hayes describes the fundamentals of mediation, moderation, and conditional process analysis using ordinary least squares regression. He also explains how to use PROCESS, a freely‑available and handy tool he invented that brings modern approaches to mediation and moderation analysis within convenient reach.
This seminar‑ a second course ‑picks up where the first edition of the book and the first course offered by GSERM leaves off. After a review of basic principles, it covers material in the second and third editions of the book as well as new material including recently published methodological research.
Topics covered include:
 Review of the fundamentals of mediation, moderation, and conditional process analysis.
 Testing whether an indirect effect is moderated and probing moderation of indirect effects.
 Partial and conditional moderated mediation.
 Mediation analysis with a multicategorical independent variable.
 Moderation analysis with a multicategorical (3 or more groups) independent variable or moderator.
 Conditional process analysis with a multicategorical independent variable
 Moderation of indirect effects in the serial mediation model.
 Mediation, Moderation, and Conditional Process Analysis in TwoInstance RepeatedMeasures Designs
 Advanced uses of PROCESS, such as how to modify a numbered model or customize your own model.
We focus primarily on research designs that are experimental or cross‑sectional in nature with continuous outcomes. We do not cover complex models involving dichotomous outcomes, latent variables, nested data (i.e., multilevel models), or the use of structural equation modeling.

 Experiences of working with data (with any software package).
 No prior knowledge on causality and causal inference is required.

 Develop research designs to address causal inference problems.
Course content
Causal questions in the form of how X influences Y are pervasive in real life. It is therefore imperative for us to know how to address these questions, especially given the “big data revolution” in the last decade. Moreover, without the understanding of causal inference, we can easily fall victim to misinformation. For example, in response to Apple’s new privacy policy on the mobile system, Facebook launched a series of fullpage newspaper ads, claiming that Apple’s new privacy policy would hurt small business advertisers. Facebook concluded that for small business advertisers, the new policy would lead to “a cut of 60% in their sales for every dollar they spend.” However, is the claim credible? How do we judge its credibility? To answer these questions, in this course, you are introduced to the exciting area of causal inference.
This course provides you with conceptual understandings, as well as tools to learn causality from data. These understandings and tools come from the rapidly developing science of causal inference. On the conceptual level, the course covers basic concepts such as causation vs. correlation, causal inference, causal identification and counterfactual. It also presents perspectives and tools to help you formalize and conceptualize causal relationships. These perspectives and tools are synergized from multiple disciplines, including statistics (e.g., Robin Causal Model or Potential Outcome Framework), computer science (e.g., Pearlian Causal Model or Causal Graph), and econometrics (e.g., identification strategies and local average treatment effect).
In this course, we will also discuss a selection of tools in causal inference. We will start with the completely randomized experiment and discuss the assignment mechanism, Fisher’s exact pvalue, and Neyman’s repeated sampling approach. From then on, we will gradually relax the assumption of complete randomization and discuss situations where the complete randomization does not hold. Specifically, we will discuss the following: First, block randomization and conditional random assignment, with a focus on matching and weighting estimators; Second, noncompliance where the random assignment fails and the local average treatment effects; Third, attrition where some outcomes are missing and the bounding approach; Fourth, research designs when the assignment mechanism is unknown to us, including the differenceindifference approach and regression discontinuity design. Moreover, in the last day of the course, we will discuss the ethics of causal inference and the assessment of the unconfoundedness assumption. As the “finale,” we will go through the most recent developments in the intersection between causal inference and machine learning, where machine learning techniques are used to address causal inference problems .
One major distinction of the course is its emphasis on practical relevance. Throughout the course, you are given cases and real data to apply what you learn to real causal inference problems. The course is split between lectures and practical sessions. Cases and data will be provided by the instructor before class.

 Understand approaches to developing an interview guide
 Gain skills in writing analytic memos, creating diagrams, and coding qualitative data
 Understand primary differences among research traditions: grounded theory, narrative analysis, and case study
 Gain skills in using qualitative analysis software
Course content
Qualitative Research Methods and Data Analysis presents strategies for analyzing and making sense of qualitative data. The course will discuss the qualitative inquiry continuum—from descriptive to interpretive—and present established qualitative research approaches such as grounded theory, narrative analysis, and case studies. The course will briefly cover research design, including discussion of design dimensions: time, comparison, and use of theory. We will briefly cover data collection strategies—primarily interviews and focus groups—but the course will largely focus on data analysis. In particular, we will consider how researchers develop codes and integrate memo writing and diagrams into a larger analytic process. Coding and memo writing are concurrent tasks that occur during an active review of interviews, documents, focus groups, and/or online data.
Analytic memo writing is a strategy for capturing analytical thinking, inscribed meaning, and cumulative evidence for condensed meanings. Memos can also resemble early writing for reports, articles, chapters, and other forms of presentation. Researchers can also mine memos for codes and use memos to build evocative themes and theory. Coding provides an analytic focus and investigative point of view; the course will illustrate specific coding practices that generate particular types of topics and concepts, such as process codes and in vivo codes. We will discuss deductive and inductive coding and how a codebook evolves—how we discern emerging codes and assess conceptual shifts during analysis. Our discussion will move from managing codes to developing code hierarchies, identifying code clusters, and building multidimensional themes. We will discuss final research products—how results are framed to underscore cognitive empathy, precision, and emergent discovery.
The course will also discuss using visual tools in analysis, such as diagramming key quotations from data to holistically present the participant’s key narratives. Visual tools can also assist in looking horizontally across many documents to identify and illustrative connective themes and link the parts (quotations or codes) to the whole (themes, documents, or participants).
The course will include daily inclass exercises—both individual and group—including exercises using software.

Examination part
Participants will be asked to read several interviews or journal entries and generate a preliminary analysis of the data using techniques discussed during the course. This examination will be due three weeks after the course ends.
Examination content
Students will have to demonstrate familiarity with the differences between grounded theory, narrative analysis, case study, and pragmatic analysis. The assignment will require them to choose one of these approaches to design a study and analyze several documents provided by the instructor. Their preliminary analysis will include memos, a codebook, diagrams, early findings, and reflection on next steps.
Prerequisites (knowledge of topic)
• Some prior knowledge in R and/or programming beneficial, but not required
Hardware
• Bring your own laptop
Software
• RStudio & R, most recent version (download free versions)
• You may want to bring your own credit card to create your own cloud accounts (for database server and certain APIs). Accounts are typically free but some require depositing a credit card number.
Course content
Online platforms such as Yelp, Twitter, Amazon, or Instagram are largescale, rich and relevant sources of data. Researchers in the social sciences increasingly tap into these data for field evidence when studying various phenomena.
In this course, you will learn how to find, acquire, store, and manage data from such sources and prepare them for followup statistical analysis for your own research.
After a short introduction into the relevance of data science skills for the social sciences, we will review R as a programming language and its basic data formats. We will then use R to program simple scrapers that systematically extract data from websites. We will use the packages rvest, httr, and RSelenium, among others, for this purpose. You will further need to learn how to read HTML, CSS, JSON, or XML codes, to use regular expressions, and to handle string, text and image data. To store the data, we will look into relational databases, (My)SQL, and related R packages. Many websites such as Twitter and Yelp offer convenient applicationprogramming interfaces (APIs) that facilitate the extraction of data and we will look into accessing them from R. Finally, we will highlight some options for feature extraction from images and text, which allows us to augment our collected data with meaningful variables we can use in our analysis.
At the end of this course, students should be able to identify valuable online data sources, to write basic scrapers, and to prepare the collected data such that they can use them for statistical analysis as part of their own research projects.
Throughout the course, students will work on a datascraping project related to their theses. This project will be presented at the final day of the course.
All data scraping code and other sources will be made available on
https://www.datascraping.org.

In the past 60 years econometrics provided us with many tools to uncover lots of different types of correlations. The technical level of this literature is impressive (see the PEF course Advanced Microeconometrics). However, at the end of day, correlations are less interesting if they do not have a causal implication. For example, the fact that smokers are more likely to die earlier than other people does not tell us much about the effect of smoking. For example, it might just be that smokers are the type of people who face more health and crime risks for quite different (social or genetic) reasons. The same problem occurs with almost any correlation of economic or financial variables. The interesting question is always whether these correlations are spurious, or whether they do tell us something about the underlying causal link of the different variables involved?
In this course we review and organize the rapidly developing literature on causal analysis in economics and econometrics and consider the conditions and methods required for drawing causal inferences from the data. Empirical applications play an important role in this course.
Active participation of PhD students participating in this course is expected. During the second part of the course, participants will conduct their own empirical study and present their results.
General structure and rules
Students activities
Active participation of the students in this course is the key to its success. Students are expected to do the following:
 Read the papers shown as ‘compulsary reading’ in the reading list BEFORE the lecture concerned with the topic.
 Each morning students will present a paper (15‑30 minutes each; depending on the number of participants) and there will be some general discussion about these papers. Students not presenting will be expected at least to sketch the papers to be able to participate in the discussion.
 Small groups of students (group size depends on number of participants) will conduct an independent empirical study (using Software of their own choice; GAUSS or STATA is recommended). In the empirical project students will show that they understood the basic concepts and are able to apply them to a ‘real life’ situation.
Grades
 Written Exam about 4 weeks after the last lecture (2 hours) (40%).
 Students’ active participation in general discussions during lectures and presentations (20%).
 Presentation of papers (20%).
 Empirical project (based on two presentations; 20%).
Prerequisites
