This function allows to calculate some statistical measures like extension and location.
1 | rocsampling(curve1.fpr, curve1.tpr, curve2.fpr, curve2.tpr, K = 100)
|
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 |
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.
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 |
