pysteps.verification.probscores.ROC_curve_compute

pysteps.verification.probscores.ROC_curve_compute(ROC, compute_area=False)

Compute the ROC curve and its area from the given ROC object.

Parameters:

ROC : dict

A ROC curve object created with ROC_curve_init.

compute_area : bool

If True, compute the area under the ROC curve (between 0.5 and 1).

Returns:

out : tuple

A two-element tuple containing the probability of detection (POD) and probability of false detection (POFD) for the probability thresholds specified in the ROC curve object. If compute_area is True, return the area under the ROC curve as the third element of the tuple.
