i have 2 models to create
and i have 2 questions related to this
1. is there an interaction model that would take care of "x1x2" or do i create a new variable x1_x2=x1*x2 and then use model y=x1 x2 x1_x2?
2.is there a way i can have SAS show me the comparison between these two models in terms of F statistics after running the second model?
