Re: st: conditional frailty model

[Matthias Pierce <emsmmpie@googlemail.com>]

Hello Jose,

Yes, i've been trying to do the same thing, but have not had a
response to my post. You can do it in R though. Prof Box-Steffensmeier
has put her R scripts online at
http://dvn.iq.harvard.edu/dvn/dv/Steffensmeier (use the search box
with the term "frailty" to find relevant documents). The basic idea is
to do a cox model, and specify strata() and frailty.gamma().

Hope this helps!

> Hello,
> I am trying to estimate  a Cox model with Conditional Frailty (as in  Box-Steffensmeier et al. 2007) along with stratification. There is a error message in stata that say that"option strata(varname) not allowed for shared frailty models". The stratification variable and id variable are different in my model. Did you resolve your problem. I have read you question in FAQ in Stata. Could you help me?
