how to retrieve robust se in coxph
see robcov in Design package. 2006/2/16, Lei Liu <ll9f at cms.mail.virginia.edu>:
Hi, I am using coxph in simulations and I want to store the "robust se" (or "se2" in frailty models) for each replicate. Is there a function to retrieve it, like vcov() for the variance estimate? Thanks!
