Hello,
Further to my previous e-mail, I think I know why I am having problems with
the initialization of model parameters in R2WinBUGS. My model.bug file
contains a portion of code which defines some pairwise odds ratios (e.g.,
or[1,2], or[1,3], or[1,4], or[2,3], or[2,4], or[3,4]) as seen below:
for (c in 1:(NT-1)) {
for (k in (c+1):NT) {
or[c,k] <- log(d[k] - d[c])
}
}
Apparently, R2WinBUGS can't recognize these values because they form an
incomplete matrix. In trying to solve this issue, I arrived at the
conclusion that R2WinBUGS may not be able to recognize WinBUGS parameters
specified as a matrix (be it complete or incomplete). Is my understanding
correct?
Any thoughts on how to overcome this predicament would be greatly
appreciated. (Thank you very much to Peter Alspach for helping me to narrow
down this problem.)
Many thanks!
Isabella
