Evaluation parameters for Culex pipiens distribution models generated using boosted regression trees from a set of environmental predictors including human population density (“BRT Pop”) and a set excluding human population density (“BRT No Pop”). Models were built using 322 presence points, and evaluated using 10 fold cross validation. “CV AUC” and “CV Deviance” are the area under the curve (AUC) and Bernoulli deviance evaluated at the withheld dataset. “Test COR” and “Test Deviance” are calculated from the predicted model values at 79 independent occurrence points not used in training the mode, and 79 background points from the same region. “Test COR” = Pearson correlation coefficient.
