Note. -2LL = -2 × Log-likelihood; df = degrees of freedom; AIC = Akaike information criterion; BIC = Bayesian information criterion; aBIC = Bayesian information criterion adjusted for sample size.

^aModels 2, 3, and 4 are compared to Model 1. Model 1 is the best fitting model, given the smallest values of -2LL, AIC, BIC, and aBIC.
