[Biomod-commits] Inconsistent GLM results

[Mathias Kuemmerlen]

Dear BIOMOD-Development Team:
 
I am using ‘BIOMOD’ version 1.1-7.02, on R version 2.15.0.
 
When performing ensemble forecasting for several species (15-30
occurrence points) I get outcomes that indicate that in some species
GLM's are not, or cannot be computed (Evualuation.results.Roc with total
score of 0.5; Var.importance with NA). Nevertheless, for most other
species it does work, even though I am while modelling with the same
environmental predictors.
 
Hopefully you can give me a hint of where the problem may be.
 
Pura vida,
