MCMC methods such as metropolis-hastings and gibbs sampling can be
programmed directly in Mathematica. The algorithms are available in
many books or articles on the subject. Lots of algorithms have been
written in S-plus or Xlispstat, but can be modified for Mathematica
Code can been found on the web. I found a MH algorithem (in S-plus),
and have been modifying it to suite each problem as they come up. I
can provide the address later if you're interested.
There are programs specifically for MCMC. One is BUGS, which is
available on the web. A search can easily bring up the address.
(search BUGS, Bayesian).
I do know of one paper called "Bayesian Statistics Using Mathematica"
the American Statistician, 1995 vol. 49. Authors Cook and Broemeling.
It might be of interest to you in exploring your specific problem. It
discusses Monte Carlo integration and sampling-importance-resampling.
(but not MCMC exactly)
