【摘要】 用方差比和广义方差比作为判定数据对Minimax线性估计影响的标准,建立了剔除一组数据时的方差比与相关系数的关系,找到了剔除多组数据时的广义方差比与Hotelling广义相关系数的联系,并讨论了剔除一组数据与剔除二组数据时的广义方差比之间的关系.更多还原

【Abstract】 The variance ratio and generalized variance ratio are used as criterion of influence of data on minimax linear estimation.The relationship between variance ratio and correlation coefficient is built when one data case is deleted.The relationship between generalized variance ratio and Hotelling generalized correlation coefficient is also found when a set of data cases is deleted.Moreover,the relationship between generalized variance ratioes when one data case is deleted or two data cases are deleted is also discussed.更多还原
