关于幂散度统计量的Bahadur有效性

On Bahadur Efficiency of Power Divergence Statistics

Peter Harremoës, Igor Vajda

摘要:

证明了当备选项序列相对于零假设序列是连续的,且每个面元的观测数增长到无穷大的速度不是很慢时,信息散度统计量比$α>1$阶幂发散统计量具有无穷大的Bahadur有效性.这改进了Harremoës和Vajda(2008)的前一个结果,其中假设零假设的序列是均匀的,并且对每个bin的观测数量的限制更严格。此外,本文还计算了其余正阶$0< α\leq 1.$的幂发散统计量的Bahadur有效性,这些阶的统计量是相互Bahadur可比的,并且都比$α> 1.$阶的统计量更具有Bahadur有效性。本文对这些技术定义和条件进行了详细的讨论,解决了一些不清楚的地方,并通过实例说明了结果。

英文摘要:

It is proved that the information divergence statistic is infinitely more Bahadur efficient than the power divergence statistics of the orders $α>1$ as long as the sequence of alternatives is contiguous with respect to the sequence of null-hypotheses and the the number of observations per bin increases to infinity is not very slow. This improves the former result in Harremoës and Vajda (2008) where the the sequence of null-hypotheses was assumed to be uniform and the restrictions on on the numbers of observations per bin were sharper. Moreover, this paper evaluates also the Bahadur efficiency of the power divergence statistics of the remaining positive orders $0< α\leq 1.$ The statistics of these orders are mutually Bahadur-comparable and all of them are more Bahadur efficient than the statistics of the orders $α> 1.$ A detailed discussion of the technical definitions and conditions is given, some unclear points are resolved, and the results are illustrated by examples.
