列联表中的乘法模型与协方差选择之间的类比

可以通过将乘法模型拟合到列联表或通过在协方差矩阵上使用协方差选择来研究特定类别的关联模式。我们证明了列联表的每个乘法模型对应于一个特定的协方差选择模型，并且我们指出了在模式解释、每个模式的检验统计数据以及变量对之间隐含的边际关联方面所产生的相似性。
A certain class of patterns of association can be investigated by fitting multiplicative models to a contingency table or by using covariance selection on a covariance matrix. We show that each multiplicative model for a contingency table corresponds to one particular covariance selection model, and we point at the resulting similarities in the interpretation of patterns, in test statistics for each pattern and in implied marginal associations among variable pairs.
