PROPORTIONAL ODDS MODELThe proportional odds model for ordinal logistic regression provides a useful extension of the binary logistic model to situations where the response variable takes on values in a set of
是基于logistic regression的一个对「有序」分类变量进行建模的模型,可以参考https://online.stat.psu.edu/stat504/node/176/。充分利用已有的资料,我想统计系课程的解释会比我在这里打一些描述地更清楚。 赞 回复 一休 (不存在的女孩) 楼主 2020-06-20 21:21:00 是基于logistic regression的一个对「有序...
proportional-odds model by the inclusion of orthogonal polynomial contrasts. We introduce the repeated measures proportional-odds logistic regression model and describe for long ordinal outcomes modifications to the generalized estimating equation methodology used for parameter estimation. We introduce data ...
In the model, when comparing two (or more) tests, each test has its own trend of ORs across studies, while the trends of two tests are (assumed to be) proportional to each other, the "proportional odds ratio" assumption. We alleviate dilemma of choosing weighting schemes such that do ...
where G is an arbitrary baseline log-odds and β is a vector of regression coefficients. Unlike the partial likelihood in Cox's model, the estimation and inference for the parameter β is much more challenging under the proportional odds model. Several contributions have been made by Dabrowska ...

The proportional odds ratio (POR) model was proposed to relax the “OR-homogeneity” assumption. The model accommodates complex missing patterns, and accounts for correlated results. In the model, when comparing two (or more) tests, each test has its own trend of ORs across studies, while th...
