ROC from Probabilities

Computes Receiver operating characteristics (ROC) based on calculated Y-probabilities and from true Y.

Documentation

Computes Receiver operating characteristics (ROC) based on calculated Y-probabilities and from true Y.

Configuration:

• pos_label

  The label of the positive class. When pos_label=None, if y_true is in {-1, 1} or {0, 1}, pos_label is set to 1, otherwise an error will be raised.

• drop_intermediate

  Whether to drop some suboptimal thresholds which would not appear on a plotted ROC curve. This is useful in order to create lighter ROC curves.

  New in version 0.17: parameter drop_intermediate.

• header as label

  Use header of Y-prob as the target label
