摘要:

概率分布间的随机序是应用概率论与统计推断中的一个重要概念. 基于交叉分类数据的趋势检验问题已被广泛地研究, 并且分层关联表广泛存在于实践中. 似然比检验方法常用于涉及随机序约束问题的检验. 对带序约束的分层关联表, 该文介绍了一种不基于模型假定的似然比检验方法, 并且给出了检验统计量的极限分布.

Abstract:

Stochastic order between probability distributions is an important concept in applied probability and statistical inference, and it is often used in many situations. Trend test based on cross-classified data was widely studied, and stratified contingency tables are common in practice. Likelihood ratio test is often used to test involving stochastic order. For stratified contingency tables with ordered categories, this paper introduces a model-free test method by using likelihood ratio test statistic and gives the asymptotic distribution of this statistic.
