I'm using the linear regression tool with the Ridge regularization. To use the Ridge regularization I have to scale the data first. Does Orange scale the data automatically? I can't find any informations about this in Orange's documentation Ridge regularization.

In python's Scikit-Learn I have to scale the data manually before using the Ridge Regression. In MATLAB is the scaling in the Ridge function included. So, do I have to scale the data manually before I'm using the Ridge Regression in orange?

Thanks for your help

Not by default, no, as shown by the normalise=False here:

class Orange.regression.linear.RidgeRegressionLearner(alpha=1.0, fit_intercept=True, normalize=False, copy_X=True, max_iter=None, tol=0.001, solver='auto', preprocessors=None)

    I would just like to add that Orange usually wraps scikit-learn's models, so the same that applies for sklean would apply for Orange. – vijolica Oct 3 at 7:09
