The data shown in Table 10.13 were collected in a follow-up study of women patients with schizophrenia (Davis, 2002). The binary response recorded at 0, 2, 6, 8, and 10 months after hospitalization was thought disorder (absent or present). The single covariate is the factor indicating whether the patient had suffered early or late onset of her condition (age of onset less than 20 years or age of onset 20 years or above). The question of interest is whether the course of the illness differs between patients with early and late onset. Investigate this question using the generalized estimating equations approach.
