- [Monika] Ever wondered how health analysts develop linear and logistic regression models? Curious about how to use R for health analytics? I'm Monika Wahi, and welcome to my course on Health Care Analytics: Regression in R, where we will use the publicly available Behavioral Risk Factor Surveillance System, or BRFSS data set to create regression models using R software. In this course, I'll teach you how to do the forward stepwise modeling process, using the BRFSS data set to develop linear and logistic regression models.
Both models will be gears towards answering a health-related hypothesis.
