WebThe area under (a ROC) curve is a measure of the accuracy of a quantitative diagnostic test. A point estimate of the AUC of the empirical ROC curve is the Mann-Whitney U estimator (DeLong et. al., 1988).The confidence interval for AUC indicates the uncertainty of the estimate and uses the Wald Z large sample normal approximation (DeLong et al., 1998). WebROC curves should be used when there are roughly equal numbers of observations for each class. If the number of observations will be equal the plotting of curves will be easier and clearer hence giving a much better and understandable output.
