1)change-point变异点
1.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.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。
2.Usually, the statistical method of F test is used to test change-point, but it can t be used to check out change-point.针对传统F检验法只能用于已知变异点的检验,而无法用于变异点的识别问题,本文提出了滑动F识别与检验法。
3.In the case of using the statistical method to check out change-point , the result may be unlikely and inconsistent with the hydrological investigated results.首先采用Hurst系数等方法对序列进行初步检验,判断序列是否存在变异;然后用多种检验方法对序列进行详细诊断,得到多种检验结果;最后对检验结果评分,计算综合权重,找出权重最大的点,并结合实际水文调查分析对该点进行确认,从而得到最可能变异点。
