Summary. The proportional odds logistic regression model is widely used for relating an ordinal outcome to a set of covariates. When the number of outcome categories is relatively large, the sample size is rela
The ordinal logistic regression model that McCullagh calls the proportional odds model is extended to models that allow non-proportional odds for a subset of the explanatory variables. The maximum likelihood method is used for estimation of parameters of general and restricted partial proportional odds...

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 ...

They show how to use ordinal regression with two equations that correspond to location and scale. The latent scale binary logistic regression of Rutter and Gatsonis [4] belong to this group. The second group contains implementations of Kardaun and Kardaun [7], and Moses et al [8]. Moses ...
If a predictor is a classifier variable with more than two classes (i.e. ordinal or nominal) then you must first use the dummy variable function to convert it to a series of binary classes.Technical validation StatsDirect optimises the log likelihood associated with a Cox regression model ...
This outcome is measured to the nearest tenth of a day in the trial but will be rounded to the closest integer such that ventilator-free days can be analyzed as an ordinal variable. There are 30 levels for ventilator-free days at day 28, specifying a patient death (− 1) and the ...
