Refer to Table 11.13 on attitudes toward legalized abortion. For the response *Y _{t}*(1=support legalization, 0=oppose.for question

**a. **A GEE analysis using unstructured working correlation gives correlation estimates 0.826 for questions 1 and 2, 0.797 for 1 and 3, and 0.832 for 2 and 3. What does this suggest about a reasonable working correlation structure?

**b. **Table 11.13 shows a GEE analysis with exchangeable working correlation. Interpret effects.

**c. **Treating the three responses for each subject as independent observations and performing ordinary logistic regression Give a heuristic explanation of why within-subject standard errors are much larger than with GEE, yet the between-subject standard error is smaller.

a) Since the co

elations are all roughly the same, we could use an exchangeable co

elation

structure.
