I would like to know what does the percentage in the variable importance list output of the Forest Based Classification in ArcGIS pro means.

Hello,

I have used the Forest based classification tool, which gives an output list with mini index and a percentage next to it. However I am not sure what the percentage means.  Is it the percentage of trees where the variable has a split impact?

Thank you!
