pyesmda.inflate_ensemble_around_its_mean

pyesmda.inflate_ensemble_around_its_mean(ensemble: ndarray[Any, dtype[float64]], inflation_factor: float) → ndarray[Any, dtype[float64]]

Inflate the given parameter ensemble around its mean.

\[m^{l+1}_{j} \leftarrow r^{l+1}\left(m^{l+1}_{j} - \frac{1}{N_{e}} \sum_{j}^{N_{e}}m^{l+1}_{j}\right) + \frac{1}{N_{e}}\sum_{j}^{N_{e}}m^{l+1}_{j}\]

Parameters

ensemble (npt.NDArray[np.float64]) – Ensemble of realization with diemnsions (\(N_{e}, N_{m}\)).

Returns

The inflated ensemble.

Return type

npt.NDArray[np.float64]
