bestThreshold

public double bestThreshold()

computeBestThreshold

public void computeBestThreshold(ConfusionMatrix.ErrMetric errM)

classError

public double[] classError()

AUC

public double AUC()

computeAUC

protected void computeAUC()

Computes area under the ROC curve. The ROC curve is computed from the confusion matrices (there is one for each computed threshold). Area under this curve is then computed as a sum of areas of trapezoids formed by each neighboring points.
