A mixed estimator interpretation of ridge regression

Vernon L. Greene

Research output: Contribution to journalArticlepeer-review


It is shown that a formal isomorphism between the ridge estimator and the homogeneous case of the Theil-Goldberger mixed estimator leads to a general interpretation of ridge regression as ordinary least squares estimation subject to a prior stochastic constraint that all slope coefficients in the model are zero. Users of ridge regression are cautioned to consider this implied specification in their use and interpretation of the technique.
