Complex Samples Ordinal Regression

The Complex Samples Ordinal Regression procedure creates a predictive model for an ordinal dependent variable for samples drawn by complex sampling methods. Optionally, you can request analyses for a subpopulation.

Using Complex Samples Ordinal Regression to Analyze Survey Results

Representatives considering a bill before the legislature are interested in whether there is public support for the bill and how support for the bill is related to voter demographics. Pollsters design and conduct interviews according to a complex sampling design.

The survey results are collected in poll_cs_sample.sav. The sampling plan used by the pollsters is contained in poll.csplan; because it makes use of a probability-proportional-to-size (PPS) method, there is also a file containing the joint selection probabilities (poll_jointprob.sav). For more information, see the topic Sample Files in Appendix A in IBM SPSS Complex Samples 19. Use Complex Samples Ordinal Regression to fit a model for the level of support for the bill based upon voter demographics.
