A . p . verbyla和w . n . venables ( 1988 )将gc模型进行了推广，得到了推广增长曲线模型( theextensionofgrowthcurvemodel简称egc模型) ，并在观察矩阵服从正态分布，各设计矩阵均为列满秩的条件下，给出了参数矩阵估计值的一种算法。 - In the late 30 or 40 years , many scholars have a lot of studies on a seemingly unrelated regression ( sdr ) system with two linear regression models , and some important results are obtained : zellner ( 1962 ) put forward two - stage estimator ( tse ) ; based on zellner " s , lin chun - shi ( 1984 ) obtained the sufficient and necessary condition of two - stage estimator ; chen chang - hua ( 1986 ) discussed the tse and its optimalities without any condition for designed - matrix x ; ulteriorly , wang song - gui and van li - qing ( 1997 ) obtained an iteration sequence of estimator by using the covariance - improved approach ; liu jin - shan ( 1994 ) , li wen and lin ju - gan ( 1997 ) generalized the covariance - improved estimator respectively
半相依回归系统是由两个误差项相关的线性回归方程组成的系统。近三、四十年来，已有很多的学者对这类半相依回归系统进行了大量的研究，作出了十分重要的成果： zellner ( 1962 )提出了所谓两步估计法；在其基础上，林春士( 1984 )得出了两步估计的充要条件，陈昌华( 1986 )讨论了对设计矩阵不作任何要求的两步估计及其优良性；进一步地，王松贵、严利清( 1997 )利用协方差改进法获得了参数的一个迭代估计序列，刘金山( 1994 ) ，李文、林举干( 1997 )则分别对协方差改进估计进行了推广。
