PipeOpVIM_regrImp: PipeOpVIM_regrImp

In NADIA: NA Data Imputation Algorithms

PipeOpVIM_regrImp

Description

Implements Regression Imputation methods as mlr3 pipeline, more about RI autotune_VIM_regrImp.

Input and Output Channels

Input and output channels are inherited from PipeOpImpute.

Parameters

The parameters include inherited from ['PipeOpImpute'], as well as:

• id :: character(1)
  Identifier of resulting object, default "imput_VIM_regrImp".

• robust :: logical(1)
  TRUE/FALSE: whether to use robust regression, default FALSE.

• mod_cat :: logical(1)
  TRUE/FALSE if TRUE for categorical variables the level with the highest prediction probability is selected, otherwise it is sampled according to the probabilities, default FALSE.

• use_imputed :: logical(1)
  TRUE/FALSe: if TURE, already imputed columns will be used to impute others, default FALSE.

• out_fill :: character(1)
  Output log file location. If file already exists log message will be added. If NULL no log will be produced, default NULL.
