SAS Enterprise Miner: Decision Tree - Test Data

I split my data set into train, validation, and test. When I run the decision tree node, I only see the results for the Train and Validation on each leaf. How do I see the results for the test data?  I tried looking at the exported data, but I only see the test data output.

The assessment in Enterprise Miner just lets you see the fit statistics for the test partition on the Model Comparison node.

I think this is to encourage you to tweak your model to improve the statistics of your validation set, and hold the test partition for unbiased comparisons.

Short answer, add a model comparison node.

 

Good luck!
