Two-stage sampling designs for external validation of personal risk models.

Statistical methods in medical research - 1 Aug 2016

Whittemore Alice S, Halpern Jerry

Abstract excerpt

We propose a cost-effective sampling design and estimating procedure for validating personal risk models using right-censored cohort data. Validation involves using each subject's covariates, as ascertained at cohort entry, in a risk model (specified independently of the data) to assign him/her a probability of an adverse outcome within a future time period. Subjects are then grouped according to the magnitudes...
