DataInvestigation_UnitInterval_71x71.png Standardize Unit Interval Tool

Use Standardize Unit Interval to perform a unit interval transformation on all the numeric fields in an input data stream. The unit interval transformation consists of subtracting the minimum value for a field from each of the original values in a field and then dividing this difference by the difference between the maximum and minimum values of the field. This results in standardized fields that each have a minimum value of zero and a maximum value of one, but are perfectly correlated with the original field values.

This tool has no configuration parameters.

Output Details

  • D anchor: Contains the standardized version of the numeric fields contained in the input stream.

  • P anchor: Contains the fields Name (the name of each transformed field), Min_Val (the field minimum value used in the standardization), and Max_Val (the field maximum value used in the standardization). This information helps to implement scoring and other similar downstream processing.
