Δχ2 (Delta Chi-Square) is the most useful statistic for comparing nested models. It compares the difference in chi-square values between the two models, with a significant value indicating that the more complex model fits significantly better than the simpler model. The other statistics listed are measures of model fit, but they cannot directly compare nested models.
