非参数法估计ROC曲线下面积,本文将采用实例数据具体介绍如何利用简单实用的非参数法估计与比较ROC 曲线下面积

ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but low specificity, strict thresholds give high spe
