Specifying Value Constraints for a Parameter Type

You can make value constraints for a parameter available during stream deployment to an external application that reads data modeling streams. This dialog box allows you to specify the values available to an external user running the stream. Depending on the data type, value constraints vary dynamically in the dialog box. The options shown here are identical to the options available for values from the Type node.

Type. Displays the currently selected measurement level. You can change this value to reflect the way that you intend to use the parameter in IBM® SPSS® Modeler.

Storage. Displays the storage type if known. Storage types are unaffected by the measurement level (continuous, nominal or flag) that you choose for work in IBM SPSS Modeler. You can alter the storage type on the main Parameters tab.

The bottom half of the dialog box dynamically changes depending on the measurement level selected in the Type field.

Continuous Measurement Levels

Lower. Specify a lower limit for the parameter values.

Upper. Specify an upper limit for the parameter values.

Labels. You can specify labels for any value of a range field. Click the Labels button to open a separate dialog box for specifying value labels.

Nominal Measurement Levels

Values. This option allows you to specify values for a parameter that will be used as a nominal field. Values will not be coerced in the IBM SPSS Modeler stream but will be used in a drop-down list for external deployment applications. Using the arrow and delete buttons, you can modify existing values as well as reorder or delete values.

Flag Measurement Levels

True. Specify a flag value for the parameter when the condition is met.

False. Specify a flag value for the parameter when the condition is not met.

Labels. You can specify labels for the values of a flag field.
