Gibbs sampling Information

["Fco. Javier Rondán Cataluña" <rondan@cica.es>]

Dear Mr./Ms:
I'm a marketing teacher in Seville University (Spain) and I'm writing my
doctoral dissertetion. I want to aplicate Gibbs Sampling to scanner
pannel data, to estimate parameters in a logit/probit model. My question
is:
Has Gibbs Sampling implemented in some kind of software?, where can I
obtain it?
That's all. Thanks.
