Regression Trees in Knime

Is it possible to create regression trees in Knime? I.e. decisions trees for predicted values (no classification)?

Currently not, but you might want to check out the Weka package in KNIME.

I have Weka package version 3.7 for Knime and still cannot create numerical regression trees, only classifications? What is required to create a numerical Random Forest model in Weka?

Just to clarify:

The KNIME AP now provides the Simple Regression Tree Learner/Predictor nodes that allow to learn regression trees.

I will answer to Your question regarding random forest in the other thread You opened ;)
