st: new package -mtreatreg-

[Partha Deb <partha.deb@hunter.cuny.edu>]

Thanks to Kit Baum, a new package, -mtreatreg- is available for install 
via ssc.  I hope the Stata community finds it useful.

-mtreatreg- fits models with multinomial treatments and continuous, 
count and binary outcomes outcomes using maximum simulated likelihood.  
The model considers the effect of an endogenously chosen 
multinomial-valued treatment on an outcome variable, conditional on two 
sets of independent variables. The outcome variable can be continuous, 
binary or integer-valued while the treatment choice is assumed to follow 
a mixed multinomial logit distribution.  The model is estimated using 
maximum simulated likelihood and the simulator uses Halton sequences. 
-mtreatreg- requires Stata 10.1.

The available outcome densities and associated conditional means are
  Gamma  - exp(xb)
  Logistic -  exp(xb)/(1+exp(xb))
  Negative Binomial-1 - exp(xb)
  Negative Binomial-2  - exp(xb)
  Normal(Gaussian) - xb

As such, -mtreatreg- renders -mtreatnb- (SJ 6(2):246-255) obsolete.

Best.
