enstools.scores.kolmogorov_smirnov

enstools.scores.kolmogorov_smirnov(reference: DataArray, target: DataArray, to_return='pvalue') → Union[DataArray, Dataset]

Compute the KS statistic of the full domain and return the pvalue .

Relies on the two-sample Kolmogorov-Smirnov implementation from scipy.

Parameters:

referencexarray.DataArray

targetxarray.DataArray

to_return: str

Can select between ‘pvalue’, ‘statistic’ or ‘both’. In this last case it will return a dataset containing both variables as a DataArrays

Returns:

result: xarray.DataArray or xarray.Dataset

A data array with the time-series of the pvalue, statistic or a dataset with both time-series.
