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.

Webfitrlinear constructed Mdl1 by training on the first four folds. Because Lambda is a sequence of regularization strengths, you can think of Mdl1 as 11 models, one for each regularization strength in Lambda. Estimate the cross-validated MSE.
