This paper formulates a mathematical model for generating receiver operating characteristic (ROC) curves without underlying data. Credit scoring practitioners know that the Gini coefficient usually ...

Classifiers are commonly evaluated using either a numeric metric, such as accuracy, or a graphical representation of performance, such as a receiver operating characteristic (ROC) curve.

But the natural interpretation of the ROC measure of accuracy and the independence of ROC curves from the probability of default are advantages unavailable to CAP analysis.
