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.

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.

PS: I can't make out the pattern of your sample data. Perhaps you were depending on the
html formatting? R-help uses simple text only.
