随机模型误差对函数模型选择的影响

The Influence on Choosing a Functional Model by Stochastic Model Error in Adjustment

  • 摘要: 测量平差问题中,函数模型误差和随机模型误差通常是同时存在的。本文揭示了两者的关系,着重讨论了两者的相互作用及其影响,特别是随机模型误差对函数模型选择的影响。同时也讨论了用来改善随机模型的"方差分量估计技术"对函数模型误差的吸收作用。最后得出了一些有益的结论。

     

    Abstract: In the paper, the relations of SME (stochastic model error) and FME (fuuctional model error), in particular, the SME's influence on choosing a functional model in adjustment, are discussed. Moreover, the effect of VCE (variance component estimating) on FME is studied. At last, some suggestions and conclusions are given.
