Hi everybody I downloaded and tested the "04_Meassuring_Variable_Importance" workflow which is found under 04_Analytics/11_Optimization/04_Meassuring_Variable_Importance in the Knime Examples.
The problem is that I used a decision tree and used the option "Force root split column" and when running the workflow it suddenly stops saying that the variable used to split the tree is not in the table.
I did a modification to the original workflow and added a nominal column which happens that is the split variable,
Please see the attached images.
I am also attaching the workflow
