摘要
文献［１］提出了聚集数据的线性模型未知参数的两种估计。本文给出了关于最小二乘估计的三种估计的相对效率，并研究了它们的性质以及与文献［２］讨论过的另一种相对效率的关系。
Two estimators of unknown parameter in linear model with aggregated data are proposed by Peter and Karsten[1].In this paper,the relative efficiencies of three estimators with respect to the least squares estimate are shown. Its properties and relation with the efficeiency,originally discussed by Duan Qingtang[2] are given.
