Hello,

I am working with zero inflated models for a current project and I am
getting wildly different results from R's zeroinfl(y ~ x, dist="negbin")
command and Stata's zinb command. Does anyone know why this may be? I find
it odd considering that zeroinfl(y ~ x, dist="poisson") gives identical to
output to Stata's zip function.

Thanks,

--david
