TABLE 1.

Comparison of goodness of fit parameter values for the four models fitted to the data: 1-region model, 2-region model, general 3-region model, and the modified 3-region model with PO₂ in region 2 set to zero.

	Goodness of Fit – No Anoxia (mean ± SD, n=13 profiles)
Model	Relative SSE	Relative RMSE	r²
1-Region	6.359 ± 6.914	2.191 ± 1.149	0.965 ± 0.028
2-Region	1.094 ± 0.119	1.031 ± 0.050	0.999 ± 0.028
3-Region	1.002 ± 0.008	1.008 ± 0.011	0.992 ± 0.007
3-Region with PO₂ in center = 0	82.903 ± 140.609	6.235 ± 6.255	0.695 ± 0.389
	Goodness of Fit – Anoxia Present (mean ± SD, n=25 profiles)
Model	Relative SSE	Relative RMSE	r²
1-Region	4.558 ± 5.594	1.877 ± 0.913	0.969 ± 0.020
