I've used OpenBugs very occasionally, too, and I've used the MCMC features of MCSim only a bit more -- perhaps occasionally is a good term. I was curious if there was MCMC work done directly in J, given the OP concern with the quantity of data and its challenges in Bugs and J's ability to deal with large quantities of data. > I expect he'll reply to your forum posting in his own right, but > it might be worth dropping Ewart Shaw a direct line.
