O'Quigley, Xu, and Stare's R2 Survival Measure

Calls survAUC::OXS().

Assumes Cox PH model specification.

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 some of these measures may be re-written and implemented directly in mlr3proba.

Dictionary

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

MeasureSurvOQuigleyR2$new()
mlr_measures$get("surv.oquigley_r2")
msr("surv.oquigley_r2")

Parameters

Empty ParamSet

Meta Information

• Type: "surv"

• Range: \([0, 1]\)

• Minimize: FALSE

• Required prediction: lp
