Hello,
I am trying to run many probit regressions and post the marginal
effects/standard errors to a new file. Here's what I am (within a
loop) trying to do:
/****************************************/
postfile `temname' mex1 mex2 sex1 sex2 using myfile.dta, replace

probit y x1 x2
mfx

post `temname' $exp
postclose `temname'
/****************************************/
My question is: what should be in Sexp? mfx returns matrices
e(Xmfx_dydx) and e(Xmfx_se_dydx) with the marginal effects and
standard errors. I don't know how to access them in this context. For
example, if instead I was using
/***************/
regress y x1 x2
/***************/
then $exp would simply be
/***************/
global $exp (_b[x1]) (_b[x2]) (_se[x1]) (_se[x2])
/***************/
but with mfx (or margin) I can't access the marginal effects/std
errors so easily.
I could also use margins, as I am running Stata 11. Any help is much
appreciated.
Thanks,
Dimitri
