摘    要：概括了配置模型的影响分析的主要成果，研究了先验信息不准确和观测误差的协方差阵扰动对最小二乘估计的影响问题．对一般公式进行了推导，并对几种特殊情况进行了详细讨论，还给出了配置模型的抗差估计及影响函数.

Abstract: Based on the main results of influence analysis in the generalized model of least square (LS) collocation,the paper investigated the effects of incorrect prior information and observation error on the LS collocation.The general expressions are derived and some special cases are discussed in detail.Robust estimates of the LS collocation are given.
