Ordinal Logistic Regression models and Statistical ...

Cornell Statistical Consulting UnitOrdinal Logistic Regression models and Statistical Software: What You Need to Know Statnews #91 Created June 2016. Last updated August 2020 Overview Ordinal Logistic Regression is a Statistical analysis method that can be used to model the relationship between an Ordinal response variable and one or more explanatory variables. An Ordinal variable is a categorical variable for which there is a clear ordering of the category levels. The explanatory variables may be either continuous or categorical. Estimating Ordinal Logistic Regression models with Statistical software is not difficult, but the interpretation of the model output can be cumbersome. Ordinal Logistic Regression is an extension of Logistic Regression (see StatNews #81) where the logit ( the log odds) of a binary response is linearly related to the independent variables.

statistical software packages use different parameterizations. Thus, great care should be taken when interpreting the output from ordinal regression models. We will consider an example to illustrate the different model parameterizations and corresponding interpretation for several commonly used statistical software packages. Example dataset
