Ridge regression, lasso, and elastic nets for linear models. 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, fit a regularized linear regression model using fitrlinear.

WebRidge regression addresses the problem of multicollinearity by estimating regression coefficients using. β ^ = ( X T X + k I) − 1 X T y. where k is the ridge parameter and I is the identity matrix. Small, positive values of k improve the conditioning of the problem and reduce the variance of the estimates.
