Well, let's suppose that c1 and c2 are your categorical variables.
Moreover, c1={1,2,3} and c4={1,2,3,4}... then I will try something like:
gen double c3= c1*10 + c2, then areg whatever, a(c3).

Asunto: Spam: st: question about subdue multiple dummy variables

Dear all,

I'd like to ask a question about dummy variables, I have 11 dummy
variables which result from the interaction of two dummies, one with 3
categories and the other with 4 categories. I like to know how to subdue
those dummies in the regression output? Something like absorb option in
areg. Anyone knows? Many thanks!
