ece-class: Class of object 'ece'

Description Objects from the Class Slots Methods References See Also

Description

Objects of class "ece" are empirical cross-entropies.

Objects from the Class

Objects can be created by calls of the form new("ece", ...) or, more commonly, via the calc.ece function which is recommended.

Slots

prior:

an arbitary array of ascending values between zero and one representing each value for which the ece is to be evaluated

ece.null:

ece values calculated assuming the observations give precisely no information about the membership of the

ece:

ece values calculated from the likelihood ratios derived from the observations which are related to membership

ece.cal:

values calculated from the likelihood ratios derived from a calibrated set using the function calibrate_set

Methods

plot

variation on the generic plot function to plot up all three sets of ece values
