pysteps.verification.detcatscores.det_cat_fct_init(thr, axis=None)

Initialize a contingency table object.

Parameters:

• thr (float) – threshold that is applied to predictions and observations in order to define events vs no events (yes/no).

• axis (None or int or tuple of ints, optional) –

  Axis or axes along which a score is integrated. The default, axis=None, will integrate all of the elements of the input arrays.

  If axis is -1 (or any negative integer), the integration is not performed and scores are computed on all of the elements in the input arrays.

  If axis is a tuple of ints, the integration is performed on all of the axes specified in the tuple.

Returns:

out – The contingency table object.

Return type:

dict
