Dear Statalist,
A small wish for version 13- implementation of Firth's method for
monotone likelihood in Cox survival models:
Heinze G and Schemper M (2001). "A Solution to the Problem of Monotone
Likelihood in Cox Regression" Biometrics 57(1), 114-119.
They have been implemented for logistic models by Joseph Coveney as
-firthlogit- but not for survival yet, and can be quite useful with
many tied failures.
cheers-
Andrew Lover
