ANOVA for stratified cox regression
...sts in a stratified analysis, *>* right?*
We have run into the same problem. In particular, we are running stratified
coxph models, but we are not able to generate a Chisq probability for both
models.

Model:
Surv(adjusted_days_60, Death_60_10) ~ strata(chol_60)
Df AIC LRT Pr(Chi)
<none> 7437.6
strata(chol_60) 0 8513.2 1075.6
As you can see, why is the probability of the Chisq - i.e., Pr(Chi) -
missing?
