Thanks, Austin,
I inquired about zero-inflated models because the regression I'm
performing is a first-stage regression in an IV model. I am
instrumenting for business profits due to nonrandom selection into
owning a business. I merely wanted a better fit to improve the
significance of my second-stage results (I'm bootstrapping my errors),
and thus am not sure I need GMM or SEM at this point in my research.
While the data isn't technically censored at zero, I have only 4 (out
of 1900) observations where profits are to the left of zero. I have a
lot of zero observations (about 1500),
Again, does anyone know of a zero-inflated Tobit command (or option
within a command) in Stata?
Best,
Katie
