I don't get this. Why is this posted to a mixed-effects model list when
there is no random effect? That said, this really is a hierarchical
model, since the sex predictor is an individual-level predictor, and
school-gender-system is a school-level predictor. In a case like this,
you're getting messed up trying to conceptualize the cross-level
interaction. My head is all messed up just trying to figure it out.
