mlr_measures_surv.rmse: Root Mean Squared Error Survival Measure

Description

Calculates the root mean squared error (RMSE).

The RMSE is defined by $$\sqrt{\frac{1}{n} \sum ((t - \hat{t})^2)}$$ where \(t\) is the true value and \(\hat{t}\) is the prediction.

Censored observations in the test set are ignored.

Dictionary
