Stepwise and Piece-wise Regression

[Bob_Nisbet]

Is there any interest at KNIME to add a Stepwise Multiple Regression algorithm, or a piece-wise Regression algorithm?

Hi @Bob_Nisbet ,

I don’t think there are any plans currently to have a specific node or algorithm for this, but you should be able to accomplish these within R or Python, or a combination of our nodes paired with the regression node.

You could use the forward and backward selection loops in pairing with this node:

Feature Selection Loop Start (1:1)

Here is a tutorial about how to do it in Python, which you can use our Python nodes in KNIME to recreate:
