Dear list:



I am using package BIOMOD and have a question concerning model prediction.



It seems that in BIOMOD, the default prediction of species distribution is
carried only on the presence and pseudo-absence points, not on the whole
background points. Which means, for example, if I have 100 presence records,
and another 1000 points were selected from the background point pool (eg.
5000 random points). The final prediction was only the 1100 points, not
5100, when I load the “pred_speciesname” file in the “pred” subfolder of
model result. My question is: is there any direct way of getting the
prediction of the whole background points from the main *Models* function,
or did I have a totally wrong understanding of prediction?



Please forgive me if the question is too silly.



Best Regard~



Marco
