| 摘 要： | 对于聚集数据的线性模型,给出了参数的广义岭估计及改进的广义岭估计的定义,并提出了广义岭估计及改进的广义岭估计在推广的欧氏模之比意义下及加权欧氏模之比意义下的二种相对效率。分别对广义岭估计及改进的广义岭估计,得到了两种相对效率的上界。

| Abstract: | For the linear model with aggregated data,In this paper,we proposed definition of the Generalized Ridge Estimators and the Improved Generalized Ridge Estimators of the parameters and two kinds of relative efficiencies of the estimators,in rate of popularize Eucliden standard a sense and in rate of weighted Euclidean standard a sense.The upper bound on the two kinds of relative efficiency are obtained. |

| Keywords: | aggregated data the linear Model generalized ridge estimators relative efficiencies |
