 Chisquare values (χ^{2}), degrees of freedom (df), and the associated P value report the significance of the model. AIC = Akaike Information Criterion; Δ_{
I
} = difference in AIC scores between the best model and subsequent model; w_{
i
} = normalized relative likelihood of the model given the data; Evidence Ratio = the relative odds that a model is the best given the data.
