Table 6.
Comparison (mean ± s.e.) of model outputs, generated by fitting the model with the 22 surviving parameter sets, and verification patterns, including results of the t-test (not significantly different at P = 0.05), and absolute and relative differences between model outputs and observations
| Pattern | Model (n = 1100) | Observation (n = 5) | t | d.f. | P | Difference | Relative difference (%)* |
|---|---|---|---|---|---|---|---|
| P1 | 7.3 ± 0.06 | 7.8 ± 3.0 | −0.17 | 4.00 | 0.88 | −0.50 | −6.36 |
| P2 | 10.82 ± 0.09 | 12.6 ± 1.5 | −1.19 | 4.03 | 0.30 | −1.78 | −14.16 |
| P3 | 66.69 ± 0.51 | 64 ± 18.9 | 0.14 | 4.00 | 0.89 | 2.69 | 4.20 |
| P4 | 47.17 ± 0.39 | 49 ± 12.3 | −0.15 | 4.01 | 0.89 | −1.83 | −3.74 |
| P5 | 3.7 ± 0.02 | 3.7 ± 0.5 | 0.005 | 4.02 | 0.996 | 0.00 | 0.00 |
| P6 | 3 | 3 | – | – | – | – | |
| P7 | † | † | – | – | – | – |
*The relative difference is calculated from model minus observation (difference) then divided by observation.
†Flush growth occurs in three seasons: spring, summer and autumn.
