st: Re: MVPROBIT
Hi to all!
I am using MVPROBIT (from ssc) to estimate a
trivariate probit regresion of the model Pr(Membership
status=1, Participation=1, Exposure to info
materials=1). After running mvprobit, I did "mfx
compute" to obtain the marginal effects, which stata
supplies after some time. I'd appreciate any help on
(1) Is it legit to use "mfx compute" after MVPROBIT?
(2) When "mfx compute" reports that certain
explanatory variables have "no effect" under the
column dy/dx, does it mean that the variables have no
statistically valid effects on the dependent variables
or that mfx cannot compute the desired estimates?
(3) Is there a way I can compute for the marginal
effects for different combinations of outcomes in the
dependent variable, say Pr(Membership status=1,
Participate=1, Exposure to info materials=0) or
Pr(Membership status=1, Participate=1|Exposure to info
materials=1). [Am looking for a similar procedure to
Stata's probit whihc allows "mfx compute,
Thanks a lot.
