.SH DESCRIPTION


This utility takes a dataset and converts a user-defined missing variable to
another to provide more meaningful analysis.
.PP
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'\fB--output_file\fP (\fB-o\fP)'.
.PP
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.csv',
and save the result to 'result.csv', we could run :
.PP
$ mlpack_mlpack_preprocess_imputer \fB--input_file\fP dataset \fB--output_file\fP result
\fB--missing_value\fP NULL \fB--dimension\fP 0 \fB--strategy\fP listwise_deletion
