public class NumericTransform extends Filter implements UnsupervisedFilter, StreamableFilter, OptionHandler
-R <index1,index2-index4,...> Specify list of columns to transform. First and last are valid indexes (default none). Non-numeric columns are skipped.
-V Invert matching sense.
-C <string> Sets the class containing transformation method. (default java.lang.Math)
-M <string> Sets the method. (default abs)
