Performing exactly the same routine with the same data on a logistic
model with family=binomial does not give this error message.
So my question is, what am I missing here?
Thanks, for any possible input
------------
I'm not a user of multcomp, so will follow with one question. Results from coxph and
coxme do not contain an intercept column. Could this be the problem?
A second possiblity is that coxme will in some cases return a bdsmatrix object as the
variance matrix (to save space). In such a case "fit$var <- as.matrix(fit$var)" might
correct the problem.
