Table 1.

QIC, ΔQIC, and model weights for the 3 models tested at each timescale (3, 6, 9, and 12 months). At each timescale, ΔQIC is the difference between a model and the model with the lowest QIC value, and the model weight is the normalized value of the model based on its ΔQIC value. All models were tested with relative intensity of use as an additional predictor variable (see text).
