R help - Sep 2005 - Survival model with cross-classified shared frailties

Dear All,

The "coxph" function in the "survival" package allows
multiple frailty
terms. In all the examples I saw, however, the frailty terms are nested. 
What will happen if I have non-nested (that is, cross-classified) frailties 
in the model? Will the model still work? Do I need to take special cares 
when specifying these models? Thanks!

Um, no, it doesn't.

This wouldn't work even if it did allow multiple frailty terms.


You may want the coxme() function in the "kinship" package.
