-
摘要: 本文首先导出了严密的F和T统计量,F统计量可用于粗差的整体检验,而T统计量可用于F检验后的各单个粗差的检验。然后给出一个算例,且与1,7中的方法进行比较。可以看到,文中提出的F-T法在理论上是严密的,在实用上是可行的,因此,它优于现有的几种方法。Abstract: This paper derives rigorous F and T statistics which are used for the global test of outliers and for the test of each outlier immediately and directly after F-test respectively.Then an example is given for the purpose of comparison with the methods in 1,7.It can be seen that the method presented in this paper is rigorous in theory,feasible in practice and better than the methods 1,7.
