Song and Zhou's AUC Survival Measure

Calls survAUC::AUC.sh().

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 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():

MeasureSurvSongAUC$new()
mlr_measures$get("surv.songAUC")
msr("surv.songAUC")

Meta Information

• Type: "surv"

• Range: \([0, 1]\)

• Minimize: FALSE

• Required prediction: lp

Method new()

Creates a new instance of this R6 class.

Usage

MeasureSurvSongAUC$new(
  integrated = TRUE,
  times,
  type = c("incident", "cumulative")
)

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.

type

(character(1))
Determines the type of score, one of: 'cumulative', 'incident'.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

MeasureSurvSongAUC$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
