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.
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")
Type: "surv"
Range: \([0, \infty)\)
Minimize: TRUE
Required prediction: response
mlr3::Measure
-> mlr3proba::MeasureSurv
-> MeasureSurvMAE
new()
Creates a new instance of this R6 class.
MeasureSurvMAE$new()
clone()
The objects of this class are cloneable with this method.
MeasureSurvMAE$clone(deep = FALSE)
deep
Whether to make a deep clone.
