Errors of Fitting of Measured Time–Activity Curves
| Model | n | Measurement twice a day | Measurement once a day | ||||
|---|---|---|---|---|---|---|---|
| Arith. mean of ln error | SD of ln error | Effect of model | Arith. mean of ln error | SD of ln error | Effect of model | ||
| Monoexponential | 64 | 1.33 | 1.28 | 2.14 | 0.89 | ||
| Biphasic | 64 | 0.58 | 1.40 | P < 0.01 | 2.15 | 0.89 | P > 0.05 |
Arith. = arithmetic.
Effect of model shows difference between monoexponential and biphasic models evaluated by paired t test.
