Model fit for all groups. The y-axis shows the normalized sum of squared residuals from the fitted data for all groups separately. The value is always normalized to the sum of squared residuals from the first model of each panel. The x-axis shows the models with random point-wise intercepts. For example, model t12+t3+t4+t5 shows a model with no random intercept at t0, a shared random intercept at t1 and t2, and different intercepts at t3, t4 and t5. The first model is always the most flexible model with separate random intercepts for t1, t2, t3, t4 and t5
