摘要
在分析了Helmert方差分量估计严密公式与简化公式迭代收敛结果一些统计性质的基础上,导出了关于收敛结果共同的求解方程,从理论上证明了两种结果的等价性,为使用简化公式提供了依据。
Based on the analysis of some statistical features about iteration convergence results,a common solving equation on rigorous formula and simplified formula of Helmert variance components estimation is derived,then the equivalence of two results is proved.The theoretical foundation of using simplified formula has been provided by this paper.
