well as the p-value of the χ2 test resulting from a comparison of −2 times the log likelihoods (−2LL) of the full and nested models. Our selection of the factor structure within each source of variance was based on agreement between AIC and BIC. This approach balances fit and parsimony, though we prioritized testing specific hypotheses rather than specifying the most parsimonious model possible. Different approaches could result in a distinct series of model-fitting decisions.
