| Abstract: | For the linear model with aggregated data,this paper proposed two kinds of biased estimators which have some superiority to the unbiased estimators in the sense of mean square error.Compared between two kinds of biased estimators,this paper proposed the estimators are better than the result on relevant documents. |
