Filtering or renaming fields

You can rename or exclude fields at any point in a stream. For example, as a medical researcher, you may not be concerned about the potassium level (field-level data) of patients (record-level data); therefore, you can filter out the K (potassium) field. This can be done using a separate Filter node or using the Filter tab on a source or output node. The functionality is the same regardless of which node it is accessed from.

• From source nodes, such as Variable File, Fixed File, Statistics File, XML, or Extension Import, you can rename or filter fields as the data are read into IBM® SPSS® Modeler.
• Using a Filter node, you can rename or filter fields at any point in the stream.
• From Statistics Export, Statistics Transform, Statistics Model, and Statistics Output nodes, you can filter or rename fields to conform to IBM SPSS Statistics naming standards.
• You can use the Filter tab in any of the above nodes to define or edit multiple response sets. See the topic Editing Multiple Response Sets for more information.
• Finally, you can use a Filter node to map fields from one source node to another.
