rocsampling {Comp2ROC}

ROC Sampling

Description

This function allows to calculate some statistical measures like extension and location.

Usage

rocsampling(curve1.fpr, curve1.tpr, curve2.fpr, curve2.tpr, K = 100)

Arguments

curve1.fpr

False positive rate vector with all points of the Curve 1

curve1.tpr

True positive rate vector with all points of the Curve 1

curve2.fpr

False positive rate vector with all points of the Curve 2

curve2.tpr

True positive rate vector with all points of the Curve 2

K

Number of sampling lines

Details

This function uses functions like areatriangles, curvesegslope, curvesegsloperef, diffareatriangles, linedistance and lineslope to calculate that measures. By default the number of sampling lines is 100, beacause it was proved by Braga that it was the optimal number.

Value

This funcion returns a list with the following components:

AUC1

Total Area of Curve 1 (using triangles)

AUC2

Total Area of Curve 2 (using triangles)

propc1

Proportion of Curve1

propc2

Proportion of Curve2

propties

Proportion of ties

locc1

Location of Curve 1

locc2

Location of Curve 2

locties

Location of Ties

K

Number of sampling lines

lineslope

Slopes of sampling lines

diffareas

Difference of area of triangles

dist1

Distance of the intersection points of Curve 1 to reference point

dist2

Distance of the intersection points of Curve 2 to reference point
