Fig. 6From: Spatio-temporal spillover risk of yellow fever in BrazilVariable importance for the National and Regional model. The median variable importance was calculated for the National, low reservoir richness (LRR), and high reservoir richness (HRR) Regional models based on 100 permutations per variable within a model. Values are the decline in AUC (∆AUC) due to permutation from the original model scaled to the largest ∆AUC within each modelBack to article page
