| 摘 要： | 本文首先给出了广义线性模型中的Ｋ－Ｌ距离和信息距离，讨论了它们的近似式及其相互关系，据此可用来检测异常点。并结合局部影响分析的思想得到了简易的诊断图，研究了回归变量的重要性以及各个观察数据对它的影响。最后给出了应用实例。

| Abstract: | This paper derives the Kullback-Leibler distance, influence distance and their approxima-tions in generalized linear models,which can be used to detect outliers. Combining the loeal influenceanalysis idea,a powerful diaguostic plot is obtained,which is sunple in computation. The imoortance of the covariates with the influences of individual observations are inveetigated. Oneexample is given as an illustration. |
