Note. CCMM = cross-classified multilevel model; CI = credible interval; MLM = multilevel model. The sample size was n = 16 172. For fixed-effect estimates, entries are parameter estimates (b) and credible intervals. All other entries are estimates (of variance) and credible intervals.
A measure of model fit reported only for cross-classified multilevel models. Higher values indicate a poorer fitting model.
Proportion of variance in the outcome attributable to neighborhoods (after adjustment for schools) or to schools (after adjustment for neighborhoods).
