Asymptotic properties of the sequential empirical ROC, PPV and NPV curves under case-control sampling

Joseph S. Koopmeiners, Ziding Feng

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 c…

Structured penalties for functional linear models---partially empirical eigenvectors for regression

Timothy W. Randolph, Jaroslaw Harezlak, Ziding Feng

One of the challenges with functional data is incorporating spatial structure, or local correlation, into the analysis. This structure is inherent in the output from an increasing…
