HandTill2001-package: Multiple Class Area under ROC Curve

Description

A very lean package implementing merely \(M\) given by Hand and Till (2001), Eq. (7).

Author

Maintainer: Andreas Dominik Cullmann

Details

\(M\) given by Hand and Till (2001) defines a multiple class version of the area under curve of the receiver operating characteristic.
