Robustness of the Trinormal Roc Surface Model: Formal Assessment via Goodness-of-Fit Testing

2025-09-12

Abstract excerpt

Receiver operating characteristic (ROC) surfaces provide a natural extension of ROC curves to three-class diagnostic problems. A key summary index is the volume under the surface (VUS), representing the probability that a randomly chosen observation from each of the three ordered groups is correctly classified. Parametric estimation of VUS typically assumes trinormality of the class distributions. However, a forma...
