摘要

在这项工作中，我们定义了对数线性模型来比较准独立或准对称模型下的几个平方列联表，并从理论上刻画了相关的马尔可夫基。通过Markov基，引入了一个精确的测试来评估两个或多个表是否适合一个公共模型。两个实际数据示例说明了这些模型在不同应用领域中的使用。

Exact tests to compare contingency tables under quasi-independence and quasi-symmetry

In this work we define log-linear models to compare several square contingency tables under the quasi-independence or the quasi-symmetry model, and the relevant Markov bases are theoretically characterized. Through Markov bases, an exact test to evaluate if two or more tables fit a common model is introduced. Two real-data examples illustrate the use of these models in different fields of applications.
