Derived Value Types
The same derived values functionality is available under Evaluation Group nodes (). Evaluation groups provide a clearer connection to the results table and more flexible data handling.
In the Model Builder, under Results, right-click Derived Values (). Select an option from the list and continue defining each derived value (see Table 21-10). All of these nodes for various derived values, except where noted, are also available as evaluation nodes under an Evaluation Group node. Also, as evaluation nodes, the default settings in the Dataset list is From parent, which is not available for the corresponding nodes under Derived Values.
Table 21-10: Derived Value Types (evaluation Nodes).
