Hai, Thank you for scikit learn compatible constrained and robust polynomial regression, it is very helpful. Addition to monotonicity constrain, I want to add a constrain to force my curve to pass through the origin (y intercept = 0). can you help me to do that? Thank you

This should be possible by eliminating the offset column of the PolynomialFeatures in sklearn terms. Currently, the code is a bit messy but let me iterate a bit. Would you be interested in a PR?
