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.
