Dear all,

I am running a IV regression using ivreg;
Code:
ivregress total i.year i.month i.HHID c.income##c.income (intake = count) [pw=mult_new].
I can obtain the marginal-effects after the second stage with;

Code:
margins, at(income = (0(100)3000)) vsquish
.

Is it possible to obtain the marginal-effects for the first-stage? Any suggestions will be highly appreciate.

Sincerely,

Chiara
