【摘要】 对数线性模型是处理高维列联表的重要方法。本文通过分析Colles骨折在性别上的年龄分布情况,介绍了对数线性模型的应用方法。讨论了选择较优模型的方法和准则。并结合实际问题,着重讨论了模型参数的估计和解释,并适当进行了模型的残差分析。最后给出了应用对数线性模型时的注意事项。更多还原

【Abstract】 Log-linear model is a important method ofanalysing multi-dimentional contingency table.With analysing age distribution occuring C-olles fracture on sex, this paper introduced theapplication of log-linear model. The methodand criteria of model selection are discussedA special effort is contributed to discuss theparameter estimation and it’s explanation,residual analysis. Finally, given some sugges-tions about application of log-linear model areproposed.更多还原
