  • If the input table contains infinity or NaN values, the input is invalid. The Scale and PartitionScale functions do not process these values, but the ScaleMap function counts the values in each column, including invalid values. The count of input values is available in the output of the ScalePrinter function.
  • If a column contains only invalid input values, the data in this column is not modified.
  • If a sequence has only one unique value, the result of the USTD, STD, RANGE, and MIDRANGE operations are NaN values because the function cannot calculate the scale.
