Introduction In this chapter, we present examples of GEE models
applied to three datasets containing correlated responses.
The examples demonstrate how to obtain odds ratios, con-
struct confidence intervals, and perform statistical tests on
the regression coefficients. The examples also illustrate the
effect of selecting different correlation structures for a
GEE model applied to the same data, and compare the
results from the GEE approach with a standard logistic
regression approach in which the correlation between
responses is ignored.
