The analysis of binary outcomes is widespread across scientific fields. This workshop introduces the basics of the most commonly used statistical model for binary outcomes, logistic regression. Some basic background on probability and odds will be provided, as well as a brief review of the model itself. This workshop then covers how to run a logistic regression in Stata, as well as estimating predictions and marginal effects, graphing model predictions, and assessing model fit. A little background in Stata is assumed.
