分类变动下有序数据回归分析的一则札记AI 解读

The effect of observation variability in the classification of an ordinal response is examined within the framework of the proportional hazards regression model for ordinal data. A model is proposed which incorporates this type of variability and the behaviour of the proportional hazards model when this new model is appropriate is examined. Four data sets are used to illustrate the practical application of the model.

基于回顾性数据的 Logistic 模型估计结果AI 解读

The logistic model (Cox, 1970, Chapter 2) has been widely used in the analysis of retrospective studies. This paper discusses two methods of analysis, one based on work by Mantel (1973) and Anderson (1972) and a second based on a conditional likelihood. The motivation for the first method is clarified and some efficiency calculations are presented.
