Complex Samples Ordinal Regression

Factors. For each selected factor,displays the ratio of the cumulative odds at each category of the

factor to the odds at the speciﬁed reference category.

Covariates. For each selected covariate, displays the ratio of the cumulative odds at the covariate’s

mean value plus thespeciﬁed units of change to the odds at the mean.

When computing odds ratios for a factor or covariate, the procedure ﬁxes all other factors at their

highest levels and all other covariatesat their means. If a factor or covariateinteracts with other

predictors in the model, then the odds ratiosdepend not only on the change in the speciﬁed

variable but also on the valuesof the variables with which it interacts. If a speciﬁed covariate

interacts with itself in the model (for example, age*age), then the odds ratios depend on both the

change in the covariate and the value of the covariate.
