Stratify sample in PROC GLM

iressa1313 — Tue, 21 Jun 2022 12:39:24 GMT

Hello, how do I simply stratify analysis by gender? My outcome variable is continuous and I have a mix of continuous and categorical predictors. I used proc glm for the whole group analysis. I thought to create a new data set for each gender and then run the analyses but I was wondering if SAS has a simpler way to accomplish this. Thanks for any help!

proc glm data= dummy;
model loglac= mddtotal age sex;
run;

I'm not 100% sure I know what you mean by "stratify" in the context of GLM modeling, but you can add SEX into the CLASS statement; you can also include interactions of SEX with AGE and MDDTOTAL, this effectively computes different intercepts and different slopes for AGE and MDDTOTAL depending on the value of SEX.
