MARTINEZ-CAMBLOR, PABLO. Comparing Diagnostic Tests from ROC Curve. Rev.Colomb.Estad. [online]. 2007, vol.30, n.2, pp. 163-176. ISSN 0120-1751.

We study the problem of comparing the power of classification of different methods from the ROC Curve. On one hand, we propose a method based on the supremum measure and, on the other hand, we study the problem of comparing two or more ROC curves from the asymptotic properties of area under ROC curves (AUC). We study the performance of proposed estimators to small samples problems with Bootstrap method and we apply them to differentiate two classes of patients of the Pediatric Intensive Care Unit (PICU) of the Hospital Central de Asturias.

Keywords : ROC curves; Sensitivity; Specificity; AUC; Bootstrap.
