mlr_measures_surv.chambless_auc: Chambless and Diao's AUC Survival Measure

Description

Calls survAUC::AUC.cd().

Assumes Cox PH model specification.

Dictionary

This Measure can be instantiated via the dictionary mlr_measures or with the associated sugar function msr():

MeasureSurvChamblessAUC$new()
mlr_measures$get("surv.chambless_auc")
msr("surv.chambless_auc")

Meta Information

• Type: "surv"

• Range: \([0, 1]\)

• Minimize: FALSE

• Required prediction: lp

Super classes

Methods

Public methods

• MeasureSurvChamblessAUC$new()

• MeasureSurvChamblessAUC$clone()

• mlr3::Measure$aggregate()

• mlr3::Measure$format()

• mlr3::Measure$help()

• mlr3::Measure$score()

• mlr3proba::MeasureSurv$print()

Method new()

Creates a new instance of this R6 class.

Usage

MeasureSurvChamblessAUC$new(integrated = TRUE, times)

Arguments

integrated

(logical(1)) If TRUE (default), returns the integrated score; otherwise, not integrated.

times

(numeric()) If integrate == TRUE then a vector of time-points over which to integrate the score. If integrate == FALSE then a single time point at which to return the score.

Method clone()

The objects of this class are cloneable with this method.

Usage

MeasureSurvChamblessAUC$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Details

All measures implemented from survAUC should be used with care, we are aware of problems in implementation that sometimes cause fatal errors in R. In future updates these measures will all be re-written and implemented directly in mlr3proba.
