Hi! I am using the mars.csv function to predict the occurrences of diatoms in the Ebro basin (Spain) and I am finding some problems that I can?t solve. I get the following error: Creating predictions for subsets... glm.fit: fitted probabilities numerically 0 or 1 occurred I am attaching the predictors + species matrix (DiatomsCV.csv), the deviance resulting from applying the mars.glm function, the MARS functions and the R code. Can anyone take a quick look at it? I am really stuck... Thank you very much in advance!
