Hi guys,

I have a rather statistical question: Having posted the
non-convergence of the ML/Probit (-ivprobit-) command before (ML
estimation not converging after the -ivprobit- where I had two
endogenous variables and for IVs).

I would like to know what the reason for this is. Especially, I was
wondering whether non-convergence was potentially someow related to
sample characteristics. Does anybody know whether this could be the
case?

Best,
Benjamin
