| 摘 要： | 有偏估计方法是近代回归分析的常用方法.本文研究聚集数据的线性模型参数的有偏估计问题,在欧氏模之比意义下给出了参数的有偏估计的一个相对效率,并在加权欧氏模之比意义下给出了参数的有偏估计的一个相对效率,并得到了这两种相对效率的上界.

| Abstract: | Biased estimate methods are basic methods of modern regression analysis.In this paper,we study the usual biased estimate problems of the linear model with aggregated data,we proposed a relative efficiency of biased estimators in rate of euclidean standard a sense,and also a relative efficiency of biased estimator in rate of weighted euclidean standard a sense.The upper bound of the two kinds of relative efficiencies are obtained. |

| Keywords: | aggregated data the linear model biased estimators relative efficiencies |
