Dear All,

I am running a svy:probit and typing margins, vce(unconditional) later.

However, I am getting the following error:


. margins, vce(unconditional)
unconditional standard errors derived assuming full estimation sample;
indepvars dropped observations from the estimation sample
r(459);


I understand this is because my covariates have some missing data, and svy:probit automatically drops those observations while running the regressions.

Is there anyway to get around this problem? I'm not using the subpop() option, but there is a if qualifier at the end of the regression:

svy: probit lfcat c.age##c.age i.female i.educ i.training i.married WApop==1, allbase
margins, vce(unconditional)

Any help would be highly appreciated.
