I am interested in estimating a two-part hurdle model (similar to the zero
inflated negative binomial model, but with a zero-truncated negbin
distribution). Does anyone know how to estimate this model in Stata? 
I am also interested in estimating a finite mixture model. I want to model
the number of visits to a physician as in Gerdtham and Trivedi's (2001)
article in Health Economics, vol. 10, pp. 565-572.
 
These two models are also discussed in Cameron and Trivedi's (1998)
"Regression analysis of count data" on pages 123-125 and 128-130.

Thanks in advance, Jose Pagan.
