Hi all,
Has anyone worked with selection models (a la Heckman) where the dependent
variable of interest requires an ordered probit? I'm familiar with the
heckman and heckprob commands in Stata, but the only models I've seen with
an ordered model have bootstrapped the standard errors. In particular, I'm
hoping someone out there has or has seen a pre-programmed routine.
Also, there was talk on this list several years ago about models with
selection based on multiple processes, where two conditions (say c1 and c2)
are observed separately (not quite Poirier), but the dependent variable is
only observed if c1=c2=1. Has anyone published on this issue?
Any advice and/or application would be greatly appreciated.
Thanks,
Erika
