this are the code i am using for the validation.
f1 <- cph(Surv(time,dead ) ~ strata(x1)+strata(x2)+strata(x3),
x=TRUE, y=TRUE, surv=TRUE, time.inc=12, data=new)
validate(f1,B=200,u=12,dxy=T)
Thanks

You did not following the posting guide.
You mixed two package; the functions you used did not match the subject
line of your e-mail.
You are attempting to validate a model containing no covariates, which
is not impossible but will be noisy.
You did not point to a function or package that claims to be able to
compute a Brier score with censored data.
