This three-part series gives a short introduction to binary logistic regression. The method can be used in situations, where the outcome (dependent) variable is binary. The series introduces the principles of the method, uses empirical examples to explain how the method is used and includes a computer workshop exercise task, which shows how to put this knowledge into practice using Stata. It is recommended that all three videos should be viewed before attempting the computer workshop task.

Part 1: Introduction to binary logistic regression

This video introduced the method and discusses how it differs from linear regression. It shows a simple example with one explanatory variable to illustrate how the method works and how the results can be interpreted using either log-odds, odds or predicted probabilities.

Part 3: Interactions in binary logistic regression

The last video of the series discusses how to interpret interaction effects in binary logistic regression models. Two options are presented: interpretation using predicted probabilities and interpretation using odds ratios.
