This package helps to assess three-class Receiver Operating
Characteristic (ROC) type data. It provides several statistical test
functions as well as a function for exploratory data analysis to
investigate classifiers allocating individuals to one of three disjoint
and ordered classes. In a single classifier assessment the
discriminatory power is compared to classification by chance. In a
comparison of two classifiers the null hypothesis corresponds to equal
discriminatory power of the two classifiers.
