摘要
探讨了广义线性模型中的log-linear模型在三维列联表中独立性模型建模的应用.首先利用Fisher-scoring算法得到了log-linear模型中回归参数的最大似然估计,并给出了模型的拟合优度检验办法;其次介绍了三维列联表中三种属性的独立性类型及它们的log-linear模型,并将其应用于具体实例,改善了现行方法中的不足.
The article makes an inquiry into the application of the log-linear model included in the generalized linear models in the independent models＂ modeling of the three-way contingency table. Firstly,maximum likelihood estimate of the regression parameter in the log-linear model is obtained by Fisher-scoring algorithm and the testing method of the goodness of fit of the model is given secondly,the types of independence and theirs log-linear models about three attributes of the three- way contingency table are introduced, and then, one example as their application is given, which imoroves the inadeauacv of the methods already existed .
