NEDAS.assim_tools.localization.correlation_based module

NEDAS.assim_tools.localization.correlation_based.gcv_localization_func(r, nens)

Correlation-based localization factor based on generalized cross-validation (cf. paper by I. Grooms)

Parameters:

r (np.ndarray) – Sample correlation coefficient.
nens (int) – Ensemble size. Must be > 2.

Returns:

Localization factor with the same shape as r.

Return type:

np.ndarray
