SAS Enterprise Miner: Looking for more detailed decision tree output summary after using Group Nodes

Hi community,

I have been using Start Groups node and End Groups node to build multiple Decision Tree based on stratification variables.

If I were to run Decision Tree node without any stratification, under Result-Output, I can expect following reports.

- Variable Summary
- Predicted and decision variables

- Variable Importance
- Tree Leaf Report
- Fit Statistics
- Assessment Score Rankings
- Assessment Score Distribution

If I were to run Decision Tree node with stratification variables using Group nodes, under Result-Output, I see following reports for each group.

- Predicted and decision variables
- Group summary
- Fit Statistics
- Assessment Score Rankings
- Assessment Score Distribution

I'm looking to access Variable importance for each models after using stratification variables but could not find where to access.

Thank you for any help.

I did get a chance to look into log created by both ways of creating multiple Decision tree, and I think Decision tree nodes do not save variable importance when ran in group nodes.
