摘要
本文利用两类不同观测值的几个算例，对两种等价权函数的抗差效果进行了比较分析。结果表明：当含粗差的观测值的多余观测分量均较大时，采用ＩＧＧＩ方案可获得良好的抗差效果；当含粗差的观测值中有多余观测分量较小的观测值，采用有界影响抗差估计能获得满意的抗差效果。
This paper compares and analyses the robustness of two kinds equivalent weight functions with a few examples. The results show that when the redundances of the observations, which contain blunders are big, the IGGI scheme has better robustness, and when some of redundances are small, the bounded influence robust estimation has better robustness.
