摘　　要：关于对数线性模型的意义，尤其是多变量无交互效应的意义，各有关文献都未作深入研究。本文就最常用的且具有代表性的三维对数线性模型的各种情形作了深入研究，给出了各模型的概率特征，尤其是利用又积比给出了无三因子交互效应的概率特征。he probability characteristics of the three-dimension log-linear models were found out. Espedcially, the strict meaning of no three-factor interactive effeCt was given out. The relahonships of any, two variables of three wereequal in all levels of another variable. The relationship was represented by the cross-product ratio.

关 键 词：对数线性模型 交互效应 叉积比
