SAS Enterprise Miner - Decision Tree: Change the Final Model Tree Branch

cgencyurek — Thu, 20 Jun 2019 21:49:00 GMT

Hi,

I'm training a decision tree model. I want to change the selected branch of tree as final model (represented in bold path in Interactive View) to produce scores based on that. How can I do it?

For example, I want to shift that bold branch selected by Enterprise Miner itself, to red branch that I choose (This image below is just an example on Home Equity data, I work on a different project now).

Thanks for all your support!

The thickness/boldness of the lines only indicates the proportion of observations in the training data that follow that path. For observations that meet the rules that follow your red line, that is the branch that will be used when scoring those. Does that make sense?

Hello Wendy,

Thank you for your response. I think I understand what you mean.

Can we make 0 / 1 check for each branch we choose when we join Score node to the Decision Tree?

I want to use the branch I choose as rule which returns True or False.
