pyPDAF.PDAF.diag_ensstats

pyPDAF.PDAF.diag_ensstats()

Computing the skewness and kurtosis of the ensemble of a given element of the state vector.

The definition used for kurtosis follows that used by [1].

Parameters:

  • dim (int) – PE-local state dimension

  • dim_ens (int) – Ensemble size

  • element (int) – ID of element to be used

  • state (ndarray[np.float64, ndim=1]) – State vector Array shape: (dim)

  • ens (ndarray[np.float64, ndim=2]) – State ensemble Array shape: (dim, dim_ens)

Returns:

  • skewness (double) – Skewness of ensemble

  • kurtosis (double) – Kurtosis of ensemble

  • status (int) – Status flag (0=success)
