Dear Statalisters
When I want -margeff- of an oprobit equation. Do I
just issue
.oprobit y x1 x2 x3 (1)
.margeff
or is it OK to issue
oprobit y x1 x2 x3, robust (2)
.margeff
Please confirm whether I can issue oprobit..., robust,
as (2) above.
Please let me know, if you require clarification.
Many Thanks in advance
Well, I just tired it with -robust-, and it works. The coefficients came
out the same whether I used robust or not, but the standard errors were a
little different, which is what I would have expected.
