在本文中,我们对奇异线性模型提出并解决参数的可估线性函数的估计效率问题,讨论了估计效率与Hotelling广义相关系数的关系,给出了估计效率的上、下界以及达到上、下界的条件.

In this paper we raise and solve the problem of estimated efficiency about parameacw for the singuiar iiuear model. Discuss the relation between the estimated efficiency and Hotelling's gexieralized correlation Coefficient, give its upper and lower bounds as well as the condition of attaining extreme value.
