Uno's C-Index Survival Measure

Description

Calls survAUC::UnoC().

Assumes random censoring.

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.

Dictionary

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

MeasureSurvUnoC$new()
mlr_measures$get("surv.unoC")
msr("surv.unoC")

Meta Information

• Type: "surv"
