mapie.metrics.kuiper_p_value(y_true: ndarray[Any, dtype[_ScalarType_co]], y_score: ndarray[Any, dtype[_ScalarType_co]]) float[source]

Compute Kuiper statistic p-value. Deduced from the corresponding statistic and CDF. It represents the probability of the observed statistic under the null hypothesis of perfect calibration.

y_trueNDArray of shape (n_samples,)

An array of ground truth.

y_scoreNDArray of shape (n_samples,)

An array of scores.
