ROC from Probabilities

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

Definition

Input ports

Y-prob table

Y-prob

Y-true table

Y-true

Output ports

roc table

roc

Configuration

Drop suboptimal thresholds (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.

Added in version 0.17: parameter drop_intermediate.

header as label (header as label)

Use header of Y-prob as the target label

Positive class label (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.
