Error-based calibration was originally suggested as an UQ validation metric by Levi et al. and is based on the expected one-to-one relationship between the root mean square error (RMSE) for the observed errors and the root mean variance (RMV). In order to get local information about the relation between errors and uncertainties, the errors and uncertainties are ordered and binned according to their predicted uncertainty. For each bin, consisting of N bin samples, the RMSE and RMV is calculated:
