Uno's AUC Survival Measure

Calls survAUC::AUC.uno().

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 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():

MeasureSurvUnoAUC$new()
mlr_measures$get("surv.uno_auc")
msr("surv.uno_auc")

Parameters

Id	Type	Default	Levels
integrated	logical	TRUE	TRUE, FALSE
times	untyped	-

Meta Information

• Type: "surv"

• Range: \([0, 1]\)

• Minimize: FALSE

• Required prediction: lp

Parameter details

• integrated (logical(1))
  If TRUE (default), returns the integrated score (eg across time points); otherwise, not integrated (eg at a single time point).

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