Coxme time dependent

i all, I am using the coxme function to fit random effects survival models. The base survival models show a typical "J" shaped curve where survival drops sharply then plateaus over time interval. I want to include a time covariate which could account for this non-linear decrease in survival over time. However, I have not found a clear way to do this in the coxme models. Any suggestions would be greatly appreciated. Below is some sample code and data. -Jared
I don't understand what you need. One of the advantages of the Cox model is that the baseline hazard function automatically accommodates such features, for both coxph and coxme.
