-lstat- apparently doesn't work after -dprobit-, but it does work after 
-probit-.  As noted in the online help,

dprobit also fits maximum-likelihood probit models.  Rather than reporting 
coefficients, dprobit reports the change in the probability for an 
infinitesimal change in each independent, continuous variable and, by 
default, the discrete change in the probability for dummy 
variables.  probit may be typed without arguments after dprobit estimation 
to see the model in coefficient form.
