I have never tried this myself. However, if there is a way, then I would
expect it to involve the -suest- module of official Stata, which carries
out Seemingly Unrelated ESTimation. To find out more, type

whelp suest

in Stata. This will point you to manual references, which give formulas
and examples.

I hope this helps.

Subject: st: testing for significant differences between coefficients in
different models

Hello all,
I couldn't find an answer to this question in the archives. I am 
analyzing two models using the same set of independent variables, one 
is a logistic regression model and the other is a Cox proportional 
hazards model. It has been suggested to me that I should do some 
post-hoc tests of the differences between the coefficients in the two 
models. Is there a way to do this in Stata, given that two different 
types of models are being estimated and the variable names are 
identical in both models?

Any help would be greatly appreciated!
Sincerely,
Wendy Regoeczi
