Why PD curves calibrated from scoring models should have a Fermi-Dirac shape?
Abstract
Scoring model performance measurement is usualy achieved by using CAP and ROC curves. We map CAP curves to a ball-box problem and we use statistical physics techniques to compute the number of CAP curves that correspond to a... [ view full abstract ]
