Although several PROCs for linear regression are available in SAS, this course uses PROC GLM, or general linear modeling. This video describes how the PROC GLM code is formulated and how to develop the model statement. Code for simple linear regression is compared with code for multiple linear regression.
- [Instructor] In this movie, I'm just going to talk about … PROC GLM for a little bit because there's a lot to it. … We're not going to run this code just yet. … I have your exercise file open, … named 505_Linear Models 1 and 2. … We aren't going to run this code until the next movie. … I just want to talk a little about PROC GLM code … and SAS in general before we get started on regression. … See this command? … This is what we call simple linear regression, … meaning linear regression … with only one independent variable. … But the thing about SAS is, it really is simple, look at it. … There's almost no code in this command. … We start with PROC GLM, specify the data set, … and then the model statement where we state Y variable … equals X variable. … Here we are saying outcome equals exposure, … or literally, the sleep variable equals … the diabetes variable. … And then the run statement. … But remember, we've used PROC GLM before, a lot. … We used it throughout the part one course. …
