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.

Key words: Stochastic order, Chi-bar-squared distribution, Likelihood ratio test, Contingency
