[Biomod-commits] reporting VarImportance

Dear biomod community,

I had a question about presenting Variable Importance in a paper. From what
I have noticed, very few SDM papers actually report such information, which
is unfortunate, since they are critical for any modeling exercise and for
understanding predictors of species distributions.

I was thinking about averaging the VarImportance scores across all my
species and models, and present them using a bar graph with SE bars. Is it
OK to do this across models, or does it need to be done for each model
separately? Also, how do I deal with the values >1, which denote negative
correlations between the original predictions and the ones with the
permuted variable?

Thank you in advance for any advice...
