Errors of Prediction 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 | 2.87 | 0.91 | 1.76 | 0.61 | ||
| Biphasic | 64 | 1.33 | 0.97 | P < 0.01 | 1.62 | 0.85 | P < 0.05 |
Arith. = arithmetic.
Effect of model shows difference between monoexponential and biphasic models evaluated by paired t test.
