Chi-square values (χ2), degrees of freedom (df), and the associated P value report the significance of the model. AIC = Akaike Information Criterion; ΔI = difference in AIC scores between the best model and subsequent model; wi = normalized relative likelihood of the model given the data; Evidence Ratio = the relative odds that a model is the best given the data.
