We have been testing the BIOMOD models against the stand-alone versions in
R (functions glm, gam, gbm, and randomForest) and while we understand that
there are many different options for running them, we cannot seem to make
them match even when trying to equalize the defaults.
Below are tables of AUC and Somer's rank correlation for two species, ran
with BIOMOD and the stand-alone models. We are trying to justify using
BIOMOD, but we cannot explain why it creates such a different output. Any
thoughts on why this is happening?
All the best
Chris
