Hi Stata,
I have a simple question about interpreting Poisson output. Suppose I
have a simple model with counts of newspapers read as the dependent
variable and gender and education as the independent variables. The two
independent variables are both dummy coded so gender is just 1 = male/0
= female and education is just 1 = college/0 = no college. If I use
poisson count gender education, irr
I get reasonable answers. The gender coefficient exponentiated tells me
the change in the count for males relative to females. Similarly for
education. What if I want to know males who went to college? Do I just
exponentiate the sum of the two coefficients? I think so. Are there
any things to watch for?
Thanks,
Walt
