摘要
1992年Khuri.A.L提出在区组设计正交条件下,混合设计模型中参数向量β(不含β_0)的区组内估计与联合估计是一致的;本文则研究了混合设计模型中位置参数β_0的三种估计,并证明了在区组设计正交条件下β_0的区组内估计β_0*、经典LSEβ_0,与联合估计β是一致的.这一工作将Khuri.A.L的结果推广到处理效应的全部待估参向量τ=(β_0,β')'在区组设计正交条件下都是一致的,对人们在混合设计中采用正交区组方案提供了更完整的理论依据。
In l992,Khuri A.L.has proved that the intra-block estimator and combinedestimators of Vector parameter β(ignoresβ_0)in mixed model are identically under the factthat the design blocks is orthogonally.In this paper,the main emphasis of the proposeddiscussion is three eatimators for the location parameterβ_0 in the Model.It is proved,thatβ_0*(the intra一block estimator),β(the ordinarg LSE)and β(the combined estimator)areidentically in orthogonally block design. The work extends Khuri’s resuIts to all parame-ter τ=(β_0,β')';and presents the reasonable basement for mixed block design using orthog-onally design.
