Dear all,
I am having a hard time to figure out a suitable test for the match between
two nominal classifications of the same set
Indeed, from the predict() function of the coxph you cannot get
directly time predictions, but only linear and exponential risk
scores. This is because, in order to get the time, a baseline hazard
has to be computed and it is not straightforward since it is implicit
in the Cox model.

Dear all,
I would like to know if it is possible to fit in R a Cox ph model with
time-dependent covariates and to account for hierarchical effects at
the same time. Additionally, I'd like also to know if it would be
possible to perform any feature selection on this model fit.
I have a data set
