Auto-Calibration Tests for Discrete Finite Regression Functions

Auto-calibration is an important property of regression functions for actuarial applications. Comparably little is known about statistical testing of auto-calibration. Denuit et al.~(2024) recently published a test with an asymptotic distribution that is not fully explicit and its evaluation needs non-parametric Monte Carlo sampling. In a simpler set-up, we present three test statistics with fully known and interpretable asymptotic distributions.
