Asymptotic Analysis for an Estimate of Regression Coefficients

CAI Xin\|min 1, HUANG Yang\|xin 2 (1.School of Sciences,Wuhan University of Technology, Wuhan 430070,Hubei,China;2.Frontier Science & Technology Research Foundation, Harvard, 1244 Boylston Street, Suite 303, Chestnut Hill, MA, 02467, USA)  
A biased estimate of regression coefficients of a linear normal model is discussed. Its asymptotic expansions of bias and mean square error are derived and the asymptotic necessary and sufficient conditions are also shown for this estimate to dominate the best linear unbiased estimate.
