weatherbench2.metrics.EnsembleMeanMSE
- class weatherbench2.metrics.EnsembleMeanMSE(ensemble_dim='realization')
Mean square error between the ensemble mean and ground truth.
Suppose we have a size n ensemble, {Xₖ}, each an iid copy of X having with mean μ and variance σ². Let Y be the ground truth. This class estimates E(X - Y)² with a bias equal to σ² / n.
