mesmer.stats.select_ar_order_scen_ens(*objs, dim, ens_dim, maxlag, ic='bic')#

Select the order of an autoregressive process and potentially calculate the median over ensemble members and scenarios

Parameters:

  • *objs (DataTree, xr.DataArrays or dict of DataArrays) – A DataTree, xr.DataArray``s or dict of ``xr.DataArray to estimate the auto regression order over.

  • dim (str) – Dimension along which to determine the order.

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

  • maxlag (int) – The maximum lag to consider.

  • ic ({‘aic’, ‘hqic’, ‘bic’}, default ‘bic’) – The information criterion to use in the selection.

Returns:

selected_ar_order (DataArray) – Array indicating the selected order with the same size as the input but dim removed.

Notes

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