Thanks to the list for the suggestions to implement CAR models with WinBUGS. I would love to see spdep include implementations of CAR via ML in the future, even though S-Plus has similar capabilities. R has a much better price, especially when being used as a teaching tool.
Does anyone have a well-documented data set and weights matrix for which authoritative results of CAR estimation exist - preferably for a single spatial parameter - that they would be willing to make available for trying this out? Roger
