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, σ^2I) 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).
