Many to One (PMML)
Transforms the values of multiple columns into a single column
depending on the include method and documents the transformation in PMML.
If set to binary the condensed
column's value is set to the name of the first column with value 1.
If the include method is maximum or minimum the value of the
condensed column is set to the name of the column which, of all
included columns, has the largest or smallest value. If the include
method is binary and all columns are 0 the condensed column will
contain a missing value.
