Re: [R] validate survival with val.surv

The documentation for val.surv tried to be clear about that. Note that val.surv is only for the case where the predictions were developed on a separate dataset, i.e., that the validation is truly 'external'. Frank yz wrote: > > Dear R users: > > I want to externally validate a model with val.su

[R] validate survival with val.surv

Dear R users: I want to externally validate a model with val.surv. Can I use only calculated survival (at 1 year) and actual survival? Or I needed the survival function and actual survival. Thanks *Yao Zhu* *Department of Urology Fudan University Shanghai Cancer Center Shanghai, China*
