Hi all,I am trying to built a species distribution model with count data (Species Richness) using a GLM. My independent variable are computed at multiple-scales. In order to select which is the best scale for my model, I first calculate a bivariate model for each of the predictor for each scale. So, I know that one possible way to select the best predictor is the use of the AUC, but I don't know if is possible to use the AUC for count data. I have read about presence/absence data (for example in the package DISMO, function evaluate) but never for count data! Any suggestions?Thank you!
