Asymptotic properties of the sequential empirical ROC, PPV and NPV curves under case-control sampling
病例对照抽样下序贯经验ROC、PPV与NPV曲线的渐近性质
The receiver operating characteristic (ROC) curve, the positive predictive value (PPV) curve and the negative predictive value (NPV) curve are three measures of performance for a continuous diagnostic biomarker. The ROC, PPV and NPV curves are often estimated empirically to avoid assumptions about the distributional form of the biomarkers. Recently, there has been a push to incorporate group sequential methods into the design of diagnostic biomarker studies. A thorough…
