Jackknife test of variable importance for Lutzomyia shannoni ecological niche model. This test determines the regularized training gain of each variable in the final model, demonstrating which variables have the greatest impact on model gain when in isolation (indicated in blue), or when omitted from the model (indicated in teal). Graph was constructed using the maximum entropy (MaxEnt) (version 3.4.4) algorithms [56]
