Course Syllabus


The course covers the topics of diagnostics for linear models, binary, multinomial, ordered, Poisson regression, along with multilevel data analysis. Students are assumed to have basic knowledge of statistics and be familiar with several conventional statistical methods, most importantly linear regression, and with the R programming environment.
Learning Objectives

Learning Objectives

  • Give an introduction to a variety of extensions of linear regression analysis widely used in modern social sciences, as well as implementations of the respective methods in R, a popular, free programming language for statistical computing. By the end of the course, students will be able to choose relevant methods of analysis, implement necessary techniques, and interpret the results of modeling.
Expected Learning Outcomes

Expected Learning Outcomes

  • Able to read and understand most academic social sciences articles that use quantitative approach
  • Able to design a quantitative social study
  • Able to use R programming language for complex statistical computations
  • Able to choose statistical methods appropriate to their data and substantive research problem

Assessment Elements

Assessment Elements

  • non-blocking Test 1
    During the class, participants are presented with a set of practical tasks that aim to test their understanding of variable transformations, diagnostics, binary and multinomial logistic modeling. The results should be submitted via email by the end of the class.
  • non-blocking Test 2
    During the class, participants are presented with a set of practical tasks that aim to test their understanding of regression analysis of different types of data. The results should be submitted via email by the end of the class.
  • non-blocking In-class assignments
    During every class, the participants are presented with a task that tests their understanding of the topic. The results should be submitted via email by the end of the class.
  • non-blocking Final exam
    The participants are presented with the tasks that test their knowledge and understanding of all topics covered during the course.
