Table 5. Multivariate analysis of three models showing change in model fit (χ2) and degrees of freedom (df) when specified parameters are dropped from full ADE model (best fitting models in bold).

	Model	df	AIC	BIC	−2LL
Cholesky	ADE	9008	3875.84	−22588.23	21891.84
Independent	ADE	9011	3876.25	−22596.21	21898.25
Common	ADE	9015	3871.08	−22609.67	21901.08

AIC = Akaike Information Criterion. AIC describes the model with best goodness-of-fit combined with parsimony. BIC = Bayesian Information Criterion. −2LL = likelihood ratio chi-square test as a measure of goodness of fit.
