To get good answers, I think you should show the exact sequence of commands
leading up to the error. I do get results with -glm- and -ssc d margeff-:

***
webuse lbw, clear
glm low age lwt race smoke ptl ht ui, family(binomial)
margeff
***

Also,

***
webuse hiv1, clear
cap which firthlogit
if _rc ssc inst firthlogit
firthlogit hiv cd4 cd8
margeff
***

leads to a much clearer error message than the one you reported...

Yes Martin, the e(depvar) command works (sorry), but I still have
problem in executing the margeff command.
