Tor Georg Jakobsen is a Professor in Political Science at the NTNU Business School. He is co-author (with Mehmet Mehmetoglu) of Applied Statistics using Stata: A Guide for the Social Sciences (Sage 2016) and has authored and co-authored numerous articles in, among others, European Sociological Review, Work, Employment & Society, Regional Studies, and Conflict Management & Peace Science. His research interest includes political behavior, sports economics, and statistical methods. Jakobsen is also winner of the 2020 Bernard Brodie Prize (together with Jo Jakobsen). He has taught quantitative courses at all levels.
Course Structure and Format
This course spans over ten days (two weeks) covering ten topics related to regression analysis. The students will get access to videos of lectures and computer labs, as well as lecture slides, lab notes, and data sets. It is a requirement that the students have access to Stata. The students are expected to watch the corresponding lectures and computer labs, as well as perform the exercises described in the lab notes using Stata before each Zoom-meeting (one meeting for each of the ten topics). In each Zoom-meeting we will go through both the theoretical material and the practical exercises, as well as having a Q&A. The last part of the meetings will be used for individual questions or the students can choose to start preparing for the following day’s topic.
This course covers regression analysis, both with continuous, ordinal, and categorical dependent variables. The focus will be on applied regression analysis, yet we will also deal with related topic like data treatment in Stata, interpretations, and how to test regression assumptions. The course includes ordinary least squares regression, logistic, ordinal, and multinomial regression, how to model and interpret non-linear effects as well as different types of statistical interactions. We will also focus on how to deal with breaches of assumptions.

The course will enable students to perform a range of regression models, to work with data treatment, and to be able to critically evaluate and interpret different types of regression models.
Students should have some knowledge about basic descriptive statistics, measures of central tendency and spread. It is also good to have some knowledge about the statistical software Stata. However, instruction and notes will be made available, so it is possible for everyone to follow (though you must work harder if you do not have previous knowledge). The course will, to a large degree, follow the structure of the book Applied Statistics using Stata. In the reading list are also included short Sage books from the series Quantitative Application in the Social Sciences that dwell deeper into the topics of logistic regression and missing data (note that these are not Stata-books but deals more with statistical theory). In the recommended readings section, I have included to Stata introduction books for those who are not very comfortable with this software (you only need one of these), as well as a book on dummy variables and some additional chapters in our main book.
