get_CLE_class {CalibratR}

get_CLE_class

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, 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.

Usage

get_CLE_class(actual, predicted, bins = 10)

Arguments

actual

vector of observed class labels (0/1)

predicted

vector of uncalibrated predictions

bins

number of bins for the equal-width binning model, default=10

Value

object of class list containing the following components:

class_1

CLE of class 1 instances

class_0

CLE of class 0 instances
