mlr_measures_surv.xu_r2: Xu and O'Quigley's R2 Survival Measure

Description

Calls survAUC::XO().

Assumes Cox PH model specification.

Dictionary

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

MeasureSurvXuR2$new()
mlr_measures$get("surv.xu_r2")
msr("surv.xu_r2")

Meta Information

• Type: "surv"

• Range: \([0, 1]\)

• Minimize: FALSE

• Required prediction: lp

Method new()

Creates a new instance of this R6 class.

Usage

MeasureSurvXuR2$new()

Method clone()

The objects of this class are cloneable with this method.

Usage

MeasureSurvXuR2$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.
