I have dichotomous data (occurrence 1 and non-occurence 0) and I want to
use the logistic regression method in order to obtain susceptibility map
of landslide occurrence.
I try to use r.regression.multi, but I am not sure to correctly define the
I try to use r.mapcalc
obtaining a map that go from -11.5 (not occurrence) to +11.5 (occurrence)
when I try to use r.regression.multi I obtain a lot of null values in
residuals and estimates map.
i do not understand why..
Thanks in advanced for the attention
