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
半相依回歸系統是由兩個誤差項相關的線性回歸方程組成的系統。近三、四十年來，已有很多的學者對這類半相依回歸系統進行了大量的研究，作出了十分重要的成果： zellner （ 1962 ）提出了所謂兩步估計法；在其基礎上，林春士（ 1984 ）得出了兩步估計的充要條件，陳昌華（ 1986 ）討論了對設計矩陣不作任何要求的兩步估計及其優良性；進一步地，王松貴、嚴利清（ 1997 ）利用協方差改進法獲得了參數的一個迭代估計序列，劉金山（ 1994 ） ，李文、林舉干（ 1997 ）則分別對協方差改進估計進行了推廣。
