Mean Absolute Error Survival Measure

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")

Meta Information
