EvaluationMeasures.FPR: EvaluationMeasures.FPR

Description

FPR of prediction

Usage

EvaluationMeasures.FPR(Real = NULL, Predicted = NULL, Positive = 1, TP = NULL, TN = NULL, FP = NULL, FN = NULL)

Arguments

Real

Real binary values of the class

Predicted

Predicted binary values of the class

Positive

Consider 1 label as Positive Class unless changing this parameter to 0

TP

Number of True Positives. Number of 1 in real which is 1 in predicted.

TN

Number of True Negatives. Number of 0 in real which is 0 in predicted.

FP

Number of False Positives. Number of 0 in real which is 1 in predicted.

FN

Number of False Negatives. Number of 1 in real which is 0 in predicted.

Value

FPR

Details

False Positive Rate is Poportional of negatives that predict as positive.

By getting the predicted and real values or number of TP,TN,FP,FN return the Fall out or False Positive Rate of model
