摘要
基于概括函数模型,从Helmert型方差分量估计原理导出处理同类观测值包含多个方差分量的估计公式,即扩展的Helmert型方差分量通用公式,并给出其简化通用公式及特殊情况。
General formulae,based on a general function model and the theory of estimating variance components of Helmert type,are derived in this paper in order to estimate different variance components from same kind of observation.The simplified formulae from general formulae and some special cases are also given.
