pyesmda.inflate_ensemble_around_its_mean

pyesmda.inflate_ensemble_around_its_mean(ensemble: ndarray[tuple[Any, ...], dtype[float64]], inflation_factor: float) → ndarray[tuple[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 (NDArrayFloat) – Ensemble of realization with diemnsions (\(N_{m}, N_{e}\)).

Returns:

The inflated ensemble.

Return type:

NDArrayFloat
