摘要
广义方差比是一个效率度量 .这里用它作为判定数据对广义压缩最小二乘估计的影响度量 ,讨论了数据对广义压缩最小二乘估计的影响问题 .
The generalized variance ratio is a measure of efficiency.It is used to assess the influence of data on generalized shrunken least squares estimate and the relationship between the generalized variance ratio and Hoetelling correlation of coefficient is built.
