Say I have 5 variables (A-E) and I would like to test all the 2-way product term interactions between them (A*B, B*C, etc). Could someone please suggest a simple program to (a) create these product term variables, and (b) test each one in Proc Logistic, including the two original variables (A,B) and the product term (A*B)? Thank you.
Specify full model as
model y = a | b | c @2 ;
See the documentation here:
Hi Reeza,
My understanding is that this will give all combinations in one model:
y=a b c a*b a*c b*c
Is that correct? I'd like to model each product term separately.
y(1)=a b a*b
y(2)=a c a*c
y(3)=b c b*c
Thanks.
