mesmer.stats._fit_auto_regression_scen_ens(*objs, dim, ens_dim, lags)#

fit an auto regression and potentially calculate the mean over ensemble members and scenarios

Parameters:

  • *objs (iterable of DataArray) – A list of xr.DataArray to estimate the auto regression over.

  • dim (str) – Dimension along which to fit the auto regression.

  • ens_dim (str) – Dimension name of the ensemble members.

  • lags (int) – The number of lags to include in the model.

Returns:

xr.Dataset – Dataset containing the estimated parameters of the intercept, the AR coeffs and the variance of the residuals.

Notes

Calculates the mean auto regression, first over the ensemble members, then over all scenarios.
