There is no implemented command to perform ridge or lasso regression? I couldn't find it in the documentation. Might be there are add-on packages I am not aware of.

    $\begingroup$ If in the next upgrade statistics is overhauled it would be a major boost for mathematica. Now it seems to be quite behind R even in major methods. $\endgroup$

    $\begingroup$ Jonathan Kinlay wrote a notebook that he published a few years ago on generalized regression; however, official support would be a good thing. jonathankinlay.com/Articles/Generalized%20Regression/… $\endgroup$ Mar 4, 2016 at 2:20
