Subject: empty cell when running GEE for binary data

hi Ozgur,
Thanks for your reply! by "empty cell" I mean there was a condition in which
all participants showed the same response (let's say response A). In other
words, the probability of A, according to the present data, was 100%; this
led to the empty cell for non-A. The odds or p(A) would be 1/0, so it's not
appropriate to use logit as the link function.
I don't think, but not sure, gee would work, but i will try the other
package you suggested!
Thanks!
Yue
