Calls survAUC::GHCI().

Assumes Cox PH model specification.

Format

R6::R6Class() inheriting from 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

MeasureSurvGonenC$new()
mlr_measures$get("surv.gonenC")
msr("surv.gonenC")
