Creating a null model in clogit in R

Question

Every time I try to create a null model for my conditional logistic regression, R crashes.

Here is a post by Matt O'Brian who also had this problem but did not ever note how it was fixed: How to create a null model for conditional logistic regression in R?

Any suggestions? Anyone?

Answer 1

Short answer, you shouldn't be able to create a null model. Old versions of either R or the survival package allowed you to do this, but they were invalid.
