An alternative method for computing the solution to (7.4.15) is to augment the design matrix X with rows λpL where LLT is the Cholesky decomposition of D, and zeros as the corresponding responses to y and then solve the least squares problem. a) Verify the algebra behind this approach. b) Can this be modified easily for varying values of λ?
