Description Usage Arguments Details Value Author(s) References See Also Examples

aucDisc calculates the Area under a Curve giving the coordinate of each point.

1	aucDisc(fpr, tpr)

`fpr`	the false positive rate (precision/abscissa) that forms the curve.
`tpr`	the true positive rate (recall/ordinate) that forms the curve.

It uses the 2nd order Taylor series in order to calculate the area under the curve.

The aucDisc returns a real number representing the Area Under the given Curve.
