ComputeSensitivity()

std::vector< Double_t > TMVA::ROCCurve::ComputeSensitivity ( const UInt_t  num_points )

private

Definition at line 176 of file ROCCurve.cxx.

ComputeSpecificity()

std::vector< Double_t > TMVA::ROCCurve::ComputeSpecificity ( const UInt_t  num_points )

private

Definition at line 140 of file ROCCurve.cxx.

GetEffSForEffB()

Double_t TMVA::ROCCurve::GetEffSForEffB	(	Double_t	effB,
		const UInt_t	num_points = 41
	)

Calculate the signal efficiency (sensitivity) for a given background efficiency (sensitivity).

Parameters

effB	Background efficiency for which to calculate signal efficiency.
num_points	Number of points used for the underlying histogram. The number of bins will be num_points - 1.

GetMvas()

GetROCCurve()

TGraph * TMVA::ROCCurve::GetROCCurve

(

const UInt_t

num_points = 100

)

Returns a new TGraph containing the ROC curve.

Sensitivity is on the x-axis, specificity on the y-axis.

Parameters

num_points

Granularity of the resulting curve. The curve will be subdivided into num_points - 1 regions where the performance of the classifier is sampled. Larger number means more accurate, but more costly, evaluation.

Definition at line 276 of file ROCCurve.cxx.

GetROCIntegral()

Double_t TMVA::ROCCurve::GetROCIntegral

(

const UInt_t

num_points = 41

)

Calculates the ROC integral (AUC)

Parameters

num_points

Granularity of the resulting curve used for integration. The curve will be subdivided into num_points - 1 regions where the performance of the classifier is sampled. Larger number means more accurate, but more costly, evaluation.
