Hi everyone,

I would like some help for a linear regression model. I'm trying to compare the outcome (scores) between 2 academic years based on participation in a program.

Would the command be: by 'program', sort : regress 'post-score var' 'pre-score var' ? Or is it: regress 'post-score var' 'program' 'pre-score var' ?

I would really appreciate any help!

Thank you
