Hi all,
I know that we can do blocking sampling/updating for FIXED effect. I now wonder if that will work for RANDOM effects in linear model or not. Will it help if I use Multi.Normal to work on this problem? Does any one has experience on this?
Besides, if I need to specify a diagonal matrix with random diagonal elements in Winbugs, what is the efficient way to do it?
Many thanks!
Best,
Jun
