Hung and Chiang's AUC Survival Measure

Source: R/MeasureSurvHungAUC.R

Calls survAUC::AUC.hc().

Assumes random censoring.

Format

R6::R6Class() inheriting from MeasureSurvAUC/MeasureSurv.

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.

Construction

MeasureSurvHungAUC$new(integrated = TRUE, times)
mlr_measures$get("surv.hungAUC")
msr("surv.hungAUC")

  • integrated :: logical(1)
    If TRUE (default), returns the integrated score; otherwise, not integrated.

  • times :: vector()
    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.

Meta Information

  • Type: "surv"

  • Range: \([0, 1]\)

  • Minimize: FALSE

  • Required prediction: lp

Fields

See MeasureSurv, as well as all variables passed to the constructor.
