    public class NumericCleaner

extends SimpleStreamFilter

A filter that 'cleanses' the numeric data from values that are too small, too big or very close to a certain value (e.g., 0) and sets these values to a pre-defined default.

Valid options are:

     -D
      Turns on output of debugging information.

     -min <double>
      The minimum threshold. (default -Double.MAX_VALUE)

     -min-default <double>
      The replacement for values smaller than the minimum threshold.
      (default -Double.MAX_VALUE)

     -max <double>
      The maximum threshold. (default Double.MAX_VALUE)

     -max-default <double>
      The replacement for values larger than the maximum threshold.
      (default Double.MAX_VALUE)

     -closeto <double>
      The number values are checked for closeness. (default 0)

     -closeto-default <double>
      The replacement for values that are close to '-closeto'.
      (default 0)

     -closeto-tolerance <double>
      The tolerance below which numbers are considered being close to
      to each other. (default 1E-6)

     -decimals <int>
      The number of decimals to round to, -1 means no rounding at all.
      (default -1)

     -R <col1,col2,...>
      The list of columns to cleanse, e.g., first-last or first-3,5-last.
      (default first-last)

     -V
      Inverts the matching sense.

     -include-class
      Whether to include the class in the cleansing.
      The class column will always be skipped, if this flag is not
      present. (default no)
