Table 1. Summary of parameter estimates and measures of “Goodness-of-fit” for exponential and bi-exponential models.

Percent relative standard error (%RSEs) for each parameter estimate is included in parentheses in left panel. Measures of “Goodness-of-fit” in the right panel are derived from either MSE or AIC method.

	A (%BrdU+ cells)	α (1/week)	B (%BrdU+ cells)	β (1/week)	MSE	AIC
Exponential model	23.4 (7.2%)	0.269 (4.4%)	-	-	0.476	496.46
Bi-exponential model	20.3 (43%)	0.549 (49%)	9.14 (110%)	0.176 (50%)	0.456	490.25
