Model -2LL Δdf Δ-2LL AIC BIC
Model 0 2622.67 - 2628.67 2642.01
Model 1 2427.32 1 195.35*** 2435.32 2453.11

Model 3 2093.12 2 1.80 2107.12 2138.25

Notes. -2LL = -2Log Likelihood, Δdf = Change of degrees of freedom between the models, Δ-2LL = Change of -2Log Likelihood between the models, AIC = Akaike’s information criterion, BIC = Bayesian information criterion of Schwarz. Model 0 = random intercept model, Model 1 = additional fixed effect for slope, Model 2 = additional random effect for slope, Model 3 = additional fixed effects for group and interaction between group and slope.
