A quick thought:  could you bootstrap the cox regression?  As long as
you're not changing the predictors each time, it should be OK.

Subject: st: exlogistic for survival data?

I am analysing 127 patients operated for thyroid cancer with 15
deaths, most of them early. Followed up for 20 years. I would like to
make multivariate analysis of difference in survival, but can not use
coxregression because of the few numbers. Can I use exlogistic to
obtain some meaningful results, ie defining predictors of death at a
certain point in time?
