Mean Absolute Error Survival Measure

Source: R/MeasureSurvMAE.R
mlr_measures_surv.mae.Rd

Calculates the mean absolute error (MAE).

The MAE is defined by $$\frac{1}{n} \sum |t - \hat{t}|$$ where \(t\) is the true value and \(\hat{t}\) is the prediction.

Censored observations in the test set are ignored.

Dictionary

This Measure can be instantiated via the dictionary mlr_measures or with the associated sugar function msr():

MeasureSurvMAE$new()
mlr_measures$get("surv.mae")
msr("surv.mae")

Parameters

IdTypeDefaultLevels
selogicalFALSETRUE, FALSE

Meta Information

  • Type: "surv"

  • Range: \([0, \infty)\)

  • Minimize: TRUE

  • Required prediction: response

Parameter details

  • se (logical(1))
    If TRUE then returns standard error of the measure otherwise returns the mean across all individual scores, e.g. the mean of the per observation scores. Default is FALSE (returns the mean).
