Abstract:

The receiver operating characteristic (ROC) curve is a tool of particular use in disease status classification with a continuous medical test (marker). Various parametric and semi-parametric models of the ROC curve have been developed to compare the discriminatory ability of a marker across covariates. These methods have focused on either modeling the marker distributions, which induces an ROC curve, or modeling the ROC curve directly (ROC-GLM). In this talk, we present analogous nonparametric approaches to ROC regression using regression trees. We compare these approaches in a simulation study, and display the results using CARTScans.
