Tiny feature request for the polynomial regression learner

Feature request: allow the Polynomial Regression Learner to fit a zeroth-order polynomial (a horizontal line). This would be consistent with the polyfit function in Matlab and Numpy. Currently first-order is the minimum.


Hi there!

Will write a ticket for it!

Tnx for engaging :wink:



Hi Ivan, that would be great! I am using it for spectrum baseline correction; sometimes I have a nasty baseline and I have to fit it with a third-order polynomial, other times the baseline is straight but it just needs to be pulled down to 0. If the polynomial regression learner could handle 0th order polynomials I could do all that with the same node.
