Do you mean you want to score a new dataset with your decision tree rules?

Hi, To the original question 1. if you are trying to score the tree on a new data set, you will not get a tree, even if you are scoring it inside EM. Because the new scoring operation does not automatically yield a target that can anchor a graph like we typically see in EM tree building process. 2. Sounds like you just want to replicate the tree graph in EM to EG environment. No, it does not happen automatically. A similar solution has been posted for proc HPSPLIT here. You can take the steps that consume the output from Proc HPSPLIT, attach to the end of your tree code to see if you can produce a graph. Some adjustments should be expected. https://communities.sas.com/t5/Mathematical-Optimization/Drawing-a-decision-tree-from-HPSPLIT/m-p/232799#U232799 Hope this helps? Jason Xin
