加权平均的一个检验统计量

A Test Statistic for Weighted Runs

Frederik Beaujean, Allen Caldwell

摘要:

介绍了一种新的基于加权偏差成功运行的检验统计量。它的使用,从独立的正态分布采样的观察详细制定。它补充了经典的$χ^{2}$检验,该检验忽略了观测值的排序,并对局部偏离预期提供了额外的灵敏度。在非参数情况下的统计量的确切分布推导和计算$p$值的算法。该算法的计算复杂性推导采用一种新的整数划分的身份。

英文摘要:

A new test statistic based on success runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic $χ^{2}$ test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute $p$-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.
