Of unknown regression coefficient ft under the linear restriction r = r and its convergence , that is : 2 . the optimalities of covariance - improved estimator sequence under three mde crlterions ; 3 求出了在线性约束r = r下未知回归系数_ 1的协方差改进估计序列,及此序列的收敛性: 2
Based on [ 4 ] , the author adds a linear restriction r = r to this sur system , and discusses the estimator and the optimalities of unknown regression coefficient ft in the sur system under the linear restriction 本文将在文献[ 4 ]的基础上,对此sur系统增加一线性约束r = r ,讨论在此线性约束r = r下半相依回归系统中未知回归系数_ 1的估计及其优良性问题。
