Dear Michael,
AFAIK survreg() cannot handle time-dependent covariates. In particular,
things are getting more complicated under the accelerated failure time
framework when it comes to the handling of time-dependent covariates.
Moreover, it is important (for both Cox and AFT models) to determi
Dear all,
I'm asking this question again as I didn't get a reply last time:
I'm doing a survival analysis with time-dependent covariates. Until now,
I have used a simple Cox model for this, specifically the coxph function
from the survival library. Now, I would like to try out an accelerated
fail
