Responses so far have sent you this way and that. Just look up -test- in STATA help.

To get to the point of using -test- for your purpose, you would need to specify a model that has group-specific slopes, or combine two regressions, one for each group, using -suest-.

Hello

Is there a procedure in stata to determine if a regression slope
(coefficient) for a predictor variable is significantly different between
groups? I would like to apply this procedure for coefficients in logistic
regression nalysis.
Thanks

Barth
