eval-functions-num-classes.md

An integer > 1, specifies the number of classes to pass to the function.

You must set this parameter if the specified input columns are of type CHAR/VARCHAR. Otherwise, the function processes this parameter according to the column data types:

  • INTEGER: By default set to 2, you must set this parameter correctly if the number of classes is any other value.

  • BOOLEAN: By default set to 2, cannot be set to any other value.
