The lowest AIC (Akaike's information criterion) value was used to determine the best fitting model (indicated in bold), except when models were not significantly different (*). Included for each model is the Akaike weight (AICW), which can be regarded as the probability that a model is the best, given the set of models. K is the number of model parameters.
