Hi all.

If I run the simple regression when x is a categorical variable ( x <- factor(x) ):

> MyFit <-coxph( Surv(start, stop, event) ~ x )

How can I get the overall p-value on x other than for each dummy variable?

> anova(MyFit)

does NOT provide that information as previously suggested on the list.

All the best,
Kare
