On testing proportional odds assumptions for proportional odds models
نویسندگان
چکیده
Proportional odds models are commonly used to model ordinal responses, but the proportional assumption may not hold in practice, leading biased inference. Tests such as score, Wald and likelihood ratio (LR) have been proposed evaluate based on without assumption. Brant has an independent binary model-based Wald-type test, Wolfe Gould extended idea propose LR-type test. This paper provides a brief review of Wolfe-Gould tests for evaluating evaluates their performance through simulation studies real data example. Sample programs provided SAS, SPSS Stata facilitate implementation these using standard statistical software packages. study highlights importance when responses. The sample this make it easy researchers apply own analyses

Variable selection for proportional odds model.
In this paper we study the problem of variable selection for the proportional odds model, which is a useful alternative to the proportional hazards model and might be appropriate when the proportional hazards assumption is not satisfied. We propose to fit the proportional odds model by maximizing the marginal likelihood subject to a shrinkage-type penalty, which encourages sparse solutions and ...
متن کاملEffect Displays for Multinomial and Proportional-odds Logit Models
An “effect display” is a graphical or tabular summary of a statistical model based on high-order terms in the model. Effect displays have previously been defined by Fox (1987, 2003) for generalized linear models (including linear models). Such displays are especially compelling for complicated models—for example, those including interactions or polynomial terms. This paper extends effect displa...
