Process Flow Diagram Logic |
The Group Processing node enables you to perform group BY processing for class variables such as GENDER. You can also use this node to analyze multiple targets, and you can process the same data source repeatedly by setting the group processing mode to index.
The Data Mining Database node enables you to create data mining databases (DMDBs) for batch processing. For non-batch processing, DMDBs are automatically created as they are needed.
Use the SAS Code node to incorporate new or existing SAS code into process flow diagrams. The ability to write SAS code enables you to include additional SAS procedures into your data mining analysis. You can also use a SAS DATA step to create customized scoring code, to conditionally process data, and to concatenate or to merge existing data sets. The node provides a macro facility to dynamically reference data sets used for training, validation, testing, or scoring and variables, such as input, target, and predict variables. After you run the SAS Code node, the results and the data sets can then be exported for use by subsequent nodes in the diagram.
Use the Control Point node to establish a control point to reduce the number of connections that are made in process flow diagrams. For example, suppose three Input Data Source nodes are to be connected to three modeling nodes. If no Control Point node is used, then nine connections are required to connect all of the Input Data Source nodes to all of the modeling nodes. However, if a Control Point node is used, only six connections are required.
Use the Subdiagram node to group or condense a portion of a process flow diagram into a subdiagram. For complex process flow diagrams, you may want to create subdiagrams to better design and control the process flow.
