Re: st: comparing regression coefficients across two models with the same dependent variables

[Orian Brook <ob11@st-andrews.ac.uk>]

Hi James

Can't help with -suest- I'm afraid, but I sympathise with your problems with
interaction effects in a non-linear model

On my supervisor's suggestion to explore and interpret interaction effects
I've been using the -prvalue- command, part of the user-written spostado by
J Scott Long, see http://www.ats.ucla.edu/stat/stata/faq/logit2by2.htm

Hope this helps
