Subject: st: Bayesian model averaging

I have recently been reading some of the Bayesian social science
literature, particularly work by Adrian Raftery, Jennifer Hoeting and
Chris Volinsky that deals with Bayesian model averaging. It seems a very
interesting avenue to pursue, but the BMA routines developed by these
authors are mostly available in S Plus (with translations into R by Ian
Painter). Does anyone know if there are any Stata routines which
implement the BMA approach?


If this sounds a bit cryptic, the description for one of the routines
(bicreg) from the R manual is as follows:

     Bayesian Model Averaging accounts for the model uncertainty
inherent in the variable selection
     problem by averaging over the best models in the model class
according to approximate posterior
     model probability.


If nothing exists in Stata, and I need to write a Stata routine myself,
do people know if there is any useful "R to Stata" documentation around
on the Net?  Apparently, the leaps algorithm used by BMA is originally
based on Fortran code, so presumably Mata can help out there.

Any advice would be most appreciated.
