WebThe ordered logit model is a regression model for an ordinal response variable. The model is based on the cumulative probabilities of the response variable: in particular, the logit of each cumulative probability is assumed to be a linear function of the covariates with Regression Coefficients constant across Response Categories. WebLoglinear models, which can also be used for ordinal variables, are not predictive models. Rather they are like chi-square models in that there is no need to specify an independent and dependent variable. In simple cases, the loglinear model is equivalent to the logit model and is more generally related to Poisson models (Agresti, 2013).
