  1. Root mean square error (RMSE) and Pearson’s correlations (r) were calculated for each of 500 iterations, then averaged for an overall measure of predictive performance. The coefficient of determination (R2) was calculated by squaring the mean correlation, and can be interpreted as the proportion of variance in observed visitation predicted by the model.
