摘要
This paper considers the empirical Bayes (EB) estimation problem for the parameter β of the linear regression model y = Xβ + ε with ε ∼ N(0, σ2 I) given β. Based on Pitman closeness (PC) criterion and mean square error matrix (MSEM) criterion, we prove the superiority of the EB estimator over the ordinary least square estimator (OLSE). © Springer-Verlag 2005.
