\title{get_CLE_class}
\usage{
get_CLE_class(actual, predicted, bins = 10)
}
\arguments{
\item{actual}{vector of observed class labels (0/1)}
\item{predicted}{vector of uncalibrated predictions}
\item{bins}{number of bins for the equal-width binning model, default=10}
}
\value{
object of class list containing the following components:
\item{class_1}{CLE of class 1 instances}
\item{class_0}{CLE of class 0 instances}
}
\description{
calculates the class-specific classification error CLE in the test set.
The method computes the deviation of the calibrated predictions of class 1 instances from their true value 1.
For class 0 instances, \code{get_CLE_class} computes the deviation from 0.
Class 1 CLE is 0 when all class 1 instances have a calibrated prediction of 1 regardless of potential miscalibration of class 0 instances.
CLE calculation is helpful when miscalibration and -classification is more cost-sensitive for one class than for the other.
