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 the specified 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 covariates at their means. If a factor or covariate interacts with other predictors in the model, then the odds ratios depend not only on the change in the specified variable but also on the values of 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.

Save Variables. This group allows you to save the model-predicted category, probability of predicted category, probability of observed category, cumulative probabilities, and predicted probabilities as new variables in the active dataset.

Export model as SPSS Statistics data. Writes a dataset in IBM® SPSS® Statistics format containing the parameter correlation or covariance matrix with parameter estimates, standard errors, significance values, and degrees of freedom. The order of variables in the matrix file is as follows.
