Use the likelihood ratio test.
After the first model write:
Store estimates A
After the second model write:
Store estimates B
Lrtest A

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
