This dataset is designed for teaching multinomial logit. The dataset is a subset of data derived from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) operated by the U.S. Centers for Disease Control, and the example presents an analysis of the strenuousness of the exercise activities someone engaged in during the previous 30 days as a function of their gender, age, and whether a respondent reports every having ever been told they have arthritis or some similar condition. The dataset file is accompanied by a teaching guide, a student guide, and a how-to guide for R.
