*The F value for the overall model and the probability of obtaining a larger F value. The overall model is a reduced quadratic that included four terms (Table 3).
**A p > 0.05 indicates no additional signal was detected that might be accounted for using a better model.
***A signal-to-noise statistic where a value greater than 4 indicates the model is adequate for making predictions.
****Model reduction by forward selection using Akaike’s Information Criterion (AICc) 10.
