| 摘 要： | 通过设计的水文变异序列生成器生成满足P-型分布及统计参数,用统计实验的方法比较分析了10种常用水文序列变异点检验方法对3类变异序列的性能检验。结果表明,秩和检验、Brown-Forsythe、有序聚类、滑动T检验、Bayesian、里海哈林检验方法对均值变异类序列检验效果明显,滑动F检验法对变差系数CV变异序列检验效率优于其他方法,各方法对偏态系数CS变异序列检验效率较低。

| Abstract: | In order to compare and analyze the performance of hydrological time variation series change-point testing method,three types of hydrological series are generated by hydrological variation series generator,and statistical experiment is used to analyze the performance of the 10 variation series testing methods.The results indicate that Rank Sum test,Brown-Forsythe test,Order Cluster analysis,sliding T test,Bayesian method,and Lee-Heghinian method can test mean variation series exactly to a certain extent,and sliding F Test have better ability to test CV variation series,but every method is not sensitive to the CS variation series. |
