I also want to learn the solution of this problem. But unfortunately, there is no clear explanation for that. I am planning to use log likelihood ratio test to compare two models and suest command. ---------------------------------------- > Date: Thu, 2 May 2013 23:25:36 +0800 > Subject: Re: st: comparing regression coefficients across two models with the same dependent variables > From: jamesstatalist@gmail.com > To: statalist@hsphsun2.harvard.edu > > Richard, > > W and Z can be different or the same.

Why? And, you aren't just comparing different models, you are comparing different models that have been estimated for different groups?
