Is there any R package that will allow one to perform a repeated measures Cox Proportional Hazards regression? I don't think coxph is set up to handle this type of problem, but I would be happy to know that I am not correct.
I am doing a study of time to hip joint replacement. As each person has two hips, a given person can appear in the dataset twice, once for the left hip and once for the right hip, and I need to account for the correlation of data from a single individual.
Thank you,
