摘要
通过多维粗差的同时定位与定值法(LEGE法)和拟准检定法(QUAD法)的比较研究,以及算例的数值分析,论述了两种探测粗差方法的不同特点,并指出了二者粗差估值的等价效果。
With the comparison between the LEGE method and QUAD method, and two examples＇ numerical analysis, the different characters of the two gross errors detection methods are discussed, and the equivalence between the two procedures is also pointed out in this paper.
