2015-09-22 Thread Therneau, Terry M., Ph.D.
I've been away for a couple weeks and am now catching up on email. The issue is that the coxme code does not have conversions built-in for all of the possible types of sparse matrix. Since it assumes that the variance matrix must be symmetric, the non-neccarily-symmetric dgCMatrix class is not

Hello All, I have a problem with running the mixed effects Cox regression model using a distance matrix from a phylogeny rather than a pedigree. I searched previous posts and didn't find any directly relevant previous posts. I am interested in using a mixed effects Cox regression model to determi
