How is the AUC used in the development and validation of risk assessment instruments?
The AUC expresses the probability that a randomly selected reoffender scores higher on a particular risk assessment tool than a randomly selected person who did not reoffend.
AUC values range from 0.5 (i.e. discrimination no better than chance) to 1.0 (i.e. perfect discrimination)..
