Thanks to Kit Baum, -fmm-, a package for estimating finite mixture models, has been added to the SSC archive. Type

. ssc describe fmm

-fmm- fits a finite mixture regression model using maximum likelihood estimation. The model is a J-component finite mixture of parametric densities, with the density within a class (j) allowed to vary in location and scale. Optionally, the mixing probabilities may be specified with covariates. -fmm- currently fits mixtures of the following distributions:
1. Gamma
2. Normal (Gaussian)
3. Negative binomial 1 & 2 (mean and constant dispersion)
4. Poisson
5. Student-t (with fixed degrees of freedom)
