proportional odds assumptionmissing datamultivariate normal imputationordinal imputation modelA popular choice when analyzing ordinal data is to consider the cumulative proportional odds model to relate the marginal probabilities of the ordinal outcome to a set of covariates. However, application of this ...
However, application of this model relies on the condition of identical cumulative odds ratios across the cut-offs of the ordinal outcome; the well-known proportional odds assumption. This paper focuses on the assessment of this assumption while accounting for repeated and missing data. In this ...

The model relaxes OR-homogeneity assumption. 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 ...
With logistic regression, one needs the assumption that the odds ratio approximates relative risk to remove the dependence on the covariates of the test and of the measures of departure from additivity. However, this problem and other difficulties disappear with a Cox proportional hazards model, ...
A SAS macro, GEEORD, has been developed for the analysis of ordinal responses with repeated measures through a regression model that flexibly allows the proportional odds assumption to apply (or not) separately for each explanatory variable. Methods and results Previously utilized in an analysis of...
when the gammas do not significantly differ from 0 the proportional odds assumption is met. Advantages of this parameterization include the fact that it is more parsimonious than the default layout. In addition, by examining the test statistics for the Gammas, you can get a feel for which ...
