A Note on Regression Analysis of Ordinal Data with Variability of Classification
在序数数据的比例风险回归模型中，研究了分类观测变异性对模型的影响，提出了一个包含这种变异性的新模型，并用四个数据集展示了其应用。
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.
