Regression Tree in RapidMiner

I just start to use RapidMiner Studio. The version I downloaded is the Trial version 6.4.

The task I have is to use a regression tree to predict a continuous variable. Is there a model operator in RapidMiner that can run such a regression tree?

I tried Decision Tree, CHAID and Random Forest operators. However, all of them gave the same error message: 'CHAID cannot handle numeric label".
Is this just a limitation to Trial version?

Thanks

Hi,

most of the decision tree implementation do not support prediction of numeric labels.

However, you can install the Weka extension from the RapidMiner Marketplace (in RapidMiner Studio, go to Help->Marketplace and search for Weka). Some of the Weka trees can solve such regression problems.

Cheers,
