Hi!

I know already form answers in this form that there is a tree algorithm for numeric dependent variables in the WEKA extentions. But I can not find it! Please could you name me the operator?

Thank you in advance!

    Hello bkulig,

     

    the operator W-RepTree should do it. Please be sure to have the Weka extension installed. There is a documentation page on this.

    You should also play with W-M5P also from the Weka library. I have obtained better results with it. There are two version of trees you can estimate with this operator. Trees with numerical predictions at the final nodes and Trees with Regression Equations at the final nodes.
