get_CLE_class function

get_CLE_class

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.

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

Returns

object of class list containing the following components: - class_1: CLE of class 1 instances

• class_0: CLE of class 0 instances
