In G&H07, the first example that leads to the motivation of multilevel models is a logit model, which we haven't yet talked about. Just ignore that detail and focus on the conceptual argument made in that section.

In G&H07, the first two examples (Section 11.2-3) that leads to the motivation of multilevel models is a logit model, which we haven't yet talked about.
