Mean Squared Error Survival Measure

Source: R/MeasureSurvMSE.R
mlr_measures_surv.mse.Rd

Calculates the mean squared error (MSE).

The MSE is defined by $$\frac{1}{n} \sum ((t - \hat{t})^2)$$ 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():

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