Complex Samples Ordinal Regression
The Complex Samples Ordinal Regression procedure performs regression analysis on a binary
or ordinal dependent variable for samples drawn by complex sampling methods. Optionally,
you can request analyses for a subpopulation.
Example. 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 accordingtoacomplexsamplingdesign.UsingComplex
Samples O rdinal Regression, you can fit a model for the level of support for the bill based upon
voter demographics.
Data. The dependent variable is ordinal. Factors are categorical. Covariates are quantitative
variables that are related to the dependent variable. Subpopulation variables can be string or
numeric but should be categorical.
Assumptions. The cases in the data file represent a sample from a complex design that should
be analyzed according to the specifications in the file selected in the Complex Samples Plan
dialog box.
