Note. The standardized proportion of variance for each parameter [and its 95% confidence interval] is provided for each model. A = additive genetic effects; D = non-additive genetic effects; C = shared environmental effects; E = nonshared environmental effects; AIC = Akaike’s Information Criterion; RMSEA = Root Mean Squared Error Approximation. x2 Δ refers to the difference in chi-square values between the full model and a reduced model. Only reduced models that had a nonsignificant chi-square were tested against the full model. The best fitting model is depicted in bold type.
