Comparing two marginal effects across two different groups

[Bibo Idris]

Hello,
I want to know what is the test which will allow me to compare marginal effects after dprobit for two models across two different samples.

My code is like this:

dprobit I $x D if H==1

dprobit I $x D if H==0

I want to see if the D is statistically significantly different across H groups.

Any help would be much appreciated

I am using STATA 14.

Thanks
