From: A global model of avian influenza prediction in wild birds: the importance of northern regions
Density plots for important variables. Density plots for the variables with the five highest variable importance scores as calculated by Random Forests in the accuracy of the predictive model of avian influenza in wild birds (A-E). The density, or the likelihood of a variable to take on a value, of AIV-positive samples for each variable is represented by red dotted lines, the AIV-negative by black solid lines.
