sklift.viz.plot_qini_curve

sklift.viz.base.plot_qini_curve(y_true, uplift, treatment, random=True, perfect=True, negative_effect=True)[source]

Plot Qini curves from predictions.

Parameters

  • y_true (1d array-like) – Ground truth (correct) labels.

  • uplift (1d array-like) – Predicted uplift, as returned by a model.

  • treatment (1d array-like) – Treatment labels.

  • random (bool) – Draw a random curve. Default is True.

  • perfect (bool) – Draw a perfect curve. Default is True.

  • negative_effect (bool) – If True, optimum Qini Curve contains the negative effects (negative uplift because of campaign). Otherwise, optimum Qini Curve will not contain the negative effects. Default is True.

Returns

Object that stores computed values.
