| 摘 要： | 研究变换数据对约束线性回归模型拟合值的影响问题，提出了Ｗｅｌｓｃｈ－Ｋｕｈ统计量，广义方差比等统计量作为变换对约束ＢＬＵ估计下拟合值影响大小的度量，得到时了影响的上界与下界，同时与广义相关系数建立了一定的联系。

| Abstract: | In this paper, we discuss the influence on fitted values in the restricted linear regression model with aggregated data. We propose Welsch Kuh statistic and generalized variance ratio to study the influence of aggregated data to fitted values, get the upper bound and lower bound of the influence, and establish the relations between these statistics and generalized correlation coefficients. |
