a) [6 points] (13.2.1) Consider a model for the log seizure rate that includes the main effects of treatment and time (where time is regarded as a categorical variable with 5 levels), and their interaction. Use generalized estimating equations (GEE), assuming separate pairwise correlations among the five responses. Construct a test of the null hypothesis of no effect of treatment on changes in the log seizure rate based on the empirical standard errors. SOLUTION
