NAME

       mlpack_preprocess_imputer - impute data

SYNOPSIS

        mlpack_preprocess_imputer -i string -m string -s string [-c double] [-d int] [-V bool] [-o string] [-h -v]

DESCRIPTION

       This  utility  takes  a dataset and converts a user-defined missing variable to another to
       provide more meaningful analysis.

       The program does not modify the original file, but instead makes a separate file  to  save
       the  output  data;  You can save the output by specifying the file name with --output_file
       (-o).

       For example, if we consider 'NULL' in dimension 0 to be a missing  variable  and  want  to
       delete  whole  row  containing the NULL in the column-wise dataset, and save the result to
       result.csv, we could run

       $  mlpack_preprocess_imputer  -i  dataset.csv  -o  result.csv  -m   NULL   -d   0   >   -s
       listwise_deletion
