Comparison Between Structural Models

Model	$\overline{\mathrm{R}\mathrm{S}\mathrm{E}}$	−2LL	BICc
one compartment	7.87	3503.67	3535.96
two compartments	14.34	3218.40	3272.22

Summary of the performance of the two evaluated models used for the structural model selection. The average residual standard error $\left(\overline{\mathrm{R}\mathrm{S}\mathrm{E}}\right)$, the log-likelihood ratio (−2LL) and the corrected Bayesian information criteria (BICc) are reported. The best model is highlighted in bold.
