You're right. My mistake. I don't know of packages (or even methods) that fits the joint distribution. However, if you're willing to settle for regression, the polymars() function in the package `polspline' claims to do this. mars() in the `mda' package will also accept matrix response, but I don't know if it just treat the multiple responses as separate univariate responses.
