Decision Tree output doesn't show Variable importance plot

Fran

Hi. I can't see within the Decision Tree browse (O, R, I) the Variable importance plot. Can you help me to fix it?

Thanks

I think i found out how to fix the problem - it is a Tool version issue. Do the following:

Add the Decision Tree Tool to the canvass
Right click on it
Select "Choose Tool Version"
You will see three options - select the second option (i.e. Decision Tree 1.0)

I ran into the same issue and it consumed a lot of time looking for solutions. I hope that helps

In your screenshot, you see the tool is operating as "RPart Decision-Tree Classification". I think this plot is only produced when the model type is "Regression" (Customize > Model Type and Sampling Weights > Regression).

From the tool documentation:

If the target field is a member of a category set, a classification tree is constructed.
If the target field is a continuous variable, a regression tree is constructed.

My test found the Variable Important plot in I output > Variable Importance.

Hi Charlie. Thank you for your clear explanation. Unhappily, your suggestion didn't work. I tried the 3 options: Auto, Classification, and Regression, none of the options showed up the Variable importance plot. It might be an Alteryx bug.

Thanks again

Thanks again
