getConfVectorForROC {arc}

Returns vector with confidences for the positive class (useful for ROC or AUC computation)

Description

Methods for computing ROC curves require a vector of confidences of the positive class, while in CBA, the confidence returned by predict with outputProbabilies = TRUE returns confidence for the predicted class. This method converts the values to confidences for the positive class

Usage

getConfVectorForROC(confidences, predictedClass, positiveClass)

Arguments

confidences

Vector of confidences

predictedClass

Vector with predicted classes

positiveClass

Positive class (String)

Value

Vector of confidence values

Examples

predictedClass = c("setosa","virginica")
confidences = c(0.9,0.6)
baseClass="setosa"
getConfVectorForROC(confidences,predictedClass,baseClass)
