st: COX
Hi all,
Do you known if it is possible to calculate a COX regression for
censured data when the number of case is equal to 0 in a categorie of a
covariate of the model.
for example:
first covariate: sex : 112 males, 85 females
second covariate: genotype : AA = 50, AB= 147, BB = 0
This give a mistake due to non convergence.
Is there a possibility to solve this problem
Thanks
