bootcov and cph error
...sing the following I get the error:
> ddist2.abr <- datadist(data2.abr)
> options(datadist='ddist2.abr')
> cph1.abr <- cph(Surv(strt3.abr,loc3.abr)~cov.a.abr+cov.b.abr,
data=data2.abr, x=T, y=T)
> boot.cph1 <- bootcov(cph1.abr, B=100, coef.reps=TRUE, pr=T)
1 Error in oosl(f, matxv(X, cof), Y) : not implemented for cph models
>
Removing coef.reps argument works fine, but I really need the
coefficients if at all possible. I cant find anything in the help files
suggesting that I cant use coef.reps in a cph model. Any help
appreciated.
Cheers
Scott
