Consider the ROC surface which is a generalization of the ROC curve for three−class diagnostic problems. In this work, we propose five criteria for the three−class ROC surface by extending the Youden index, the sum of sensitivity and specificity, the maximum vertical distance, the amended closest-to-(0,1) and the true rate. It may be concluded that these five criteria can be expressed as a func...
