| 摘 要： | 针对传统同质点探测方法 KS检验检验效率低的问题,提出一种利用伽马分布作为前验信息及Bootstrap区间估计探测同质点的方法,实验表明:本文提出的方法能够有效地探测完成同质点的探测,有效地提高了数据检验的效率,为相干性的无偏估计提供了较好的条件。

| Abstract: | Aiming at the problem of low efficiency of traditional Homomorphic Detection(KS) test,this paper proposes a method for detecting Homogeneous points based on the gamma distribution and Bootstrap interval estimation. Experiments show that method this paper proposed can effectively detect high coherence point and can detect the same point of homogeneity. This method effectively improved the efficiency of data inspection and laid the foundation for unbiased coherence estimation. |
