mlr_measures_surv.mse: Mean Squared Error Survival Measure

In mlr3proba: Probabilistic Supervised Learning for 'mlr3'

Mean Squared Error Survival Measure

Description

Calculates the mean squared error (MSE).

The MSE is defined by

1/n ∑ ((t - t*)^2)

where t is the true value and 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():

MeasureSurvMSE$new()
mlr_measures$get("surv.mse")
msr("surv.mse")

Meta Information
