Uno's TNR Survival Measure

Source: R/MeasureSurvUnoTNR.R
mlr_measures_surv.uno_tnr.Rd

Calls survAUC::spec.uno().

Assumes random censoring.

times and lp_thresh are arbitrarily set to 0 to prevent crashing, these should be further specified.

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():

MeasureSurvUnoTNR$new()
mlr_measures$get("surv.uno_tnr")
msr("surv.uno_tnr")

Parameters

IdTypeDefaultRange
timesnumeric-\([0, \infty)\)
lp_threshnumeric0\((-\infty, \infty)\)

Meta Information

  • Type: "surv"

  • Range: \([0, 1]\)

  • Minimize: FALSE

  • Required prediction: lp

Parameter details

  • times (numeric())
    A vector of time-points at which we calculate the TPR/TNR scores.

  • lp_thresh (numeric(1))
    Determines the cutoff threshold of the linear predictor in the calculation of the TPR/TNR scores.
