Ridge regression, lasso, elastic nets

For greater accuracy on low- through medium-dimensional data sets, implement least-squares regression with regularization using lasso or ridge.

For reduced computation time on high-dimensional data sets that fit in the MATLAB® Workspace, fit a regularized linear regression model using fitrlinear.
