linedistance {Comp2ROC} | R Documentation |
Intersection Points
Description
This function allows to calculate the intersection points between the ROC curve and the sampling lines. Also calculates the distance between this points and the reference point.
Usage
linedistance(curve.fpr, curve.tpr, curve.segslope, curve.slope, line.slope, ref.point)
Arguments
curve.fpr |
False positive rate vector with all points of the given Curve |
curve.tpr |
True positive rate vector with all points of the given Curve |
curve.segslope |
Vector with all segments slope of the ROC curves |
curve.slope |
Vector with all the slope of all segments that connect the ROC curve with the reference point |
line.slope |
Vector with the slope of all sampling lines |
ref.point |
Reference point where we start drawing the sampling lines |
Value
This function returns a list with:
dist |
Vector with distances between the intersection points and the reference points |
x |
Vector with all x coordinates of intersection points |
y |
Vector with all y coordinates of intersection points |
