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. See the topic Renaming or Filtering Fields for IBM SPSS Statistics for more information.
• 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.
