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。
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 .
