New statistical method decomposes forecast scores into miscalibration, discrimination, and uncertainty

A new statistical inference method has been developed to decompose scoring functions for predictive assessments into three components: miscalibration, discrimination, and uncertainty. This approach, applicable to general point forecasts, ensures non-negative decomposition terms and enables asymptotic inference under model misspecification. The framework connects to the classical Mincer-Zarnowitz regression and offers enhanced tests for forecast calibration and discrimination, providing deeper insights into financial risk models and exposing shortcomings in current banking regulation.
