I. Overview (page 542)
II–IV. Examples (pages 542–557)
A. Three examples were presented in detail:
i. Infant Care Study
ii. Aspirin–Heart Bypass Study
iii. Heartburn Relief Study
B. Key points from the examples:
i. The choice of correlation structure may
affect both the coefficient estimate and
the standard error of the estimate,
although standard errors are more
commonly impacted
ii. Which correlation structure(s) should be
specified depends on the underlying
assumptions regarding the relationship
between responses (e.g., ordering or time
interval)
iii. Interpretation of regression coefficients
(in terms of odds ratios) is the same as in
standard logistic regression
