st: Marginal Effects after xtprobit

["Pavlos C. Symeou" <p.symeou@gmail.com>]

Dear Statalisters,

I run a regression model with - xtprobit, re- and after the estimation I 
ask for the marginal effects with the command - mfx - . The model 
coefficients from both the commands are exactly the same. Would anyone 
know why I get these results?
Best regards,

Pavlos
