CindexCR

The C-index (Concordance index) of the prognostic model in the presence of competing risks according to Marcel, W et al.(2014).

An implementation of popular evaluation metrics that are commonly used in survival prediction including Concordance Index, Brier Score, Integrated Brier Score,
Integrated Square Error, Integrated Absolute Error and Mean Absolute Error.
