mlr3proba (version 0.2.1)

mlr_pipeops_trafotask_regrsurv: PipeOpTaskRegrSurv

Description

Transform TaskRegr to TaskSurv.

Input and Output Channels

Input and output channels are inherited from PipeOpTaskTransformer.

The output is the input TaskRegr transformed to a TaskSurv.

State

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

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.
