摘要
通过分析和比较目前用于抗差估计中“最小值和法”和“IGG方案”理论在测量中应用的一般过程,讨论了粗差的检测和定位问题。亦即如何正确找出一组观测值中的粗差并消除粗差对平差结果的影响。通过大量的统计数据得出了概率意义更明确、计算更简便的改进计算方法,在指导实际生产中可以避免许多错误的产生。
It analyzes and compares the common process using the ＂ minimum sum＂ and ＂ IGG ＂ theories that are now used in anti - error estimating, and discusses the checking and fixing position of rough error and how to find out the rough error in a＇ group of got data and eliminating its influence to the counting results, Having analyzed a lot of statistic data we have got a revised method which is more clear on probability signification and easily, simply to be counted, and in practice it avoided many mistakes to be happened.
