mlr3proba (version 0.4.9)

mlr_pipeops_trafopred_regrsurv: PipeOpPredRegrSurv

Description

Transform PredictionRegr to PredictionSurv.

Input and Output Channels

Input and output channels are inherited from PipeOpPredTransformer.

The output is the input PredictionRegr transformed to a PredictionSurv. Censoring can be added with the status hyper-parameter. se is ignored.

State

The $state is a named list with the $state elements inherited from PipeOpPredTransformer.

Parameters

The parameters are

• status :: (numeric(1)) If NULL then assumed no censoring in the dataset. Otherwise should be a vector of 0/1s of same length as the prediction object, where 1 is dead and 0 censored.
