Abstract:
|
Nested case-control design provides a cost-effective cohort sampling strategy in biomarker research. We propose estimating procedures to evaluate the prognostic accuracy of a novel biomarker for predicting future events with censored failure time outcome under a matched nested case-control design. In the presence of missing information on the biomarker measurements, we develop consistent estimators for time-dependent classification and predictive accuracy measures based on the idea of inverse probability weighting.
