Hi all,
I'm working with some data: 54 variables and a column of classes, each observation as one of a possible seven different classes:
> var.can3<-lda(x=dados[,c(1:28,30:54)],grouping=dados[,55],CV=TRUE)
Warning message:
In lda.default(x, grouping, ...) : variables are collinear

unexpected GAM result - at least for me!
...ng to model presence / absence (presence = 1, absence = 0) of a species using some lidar metrics (i have 4 of these). I am using different models and such .... and when i used gam i got this very weird (for me) result which i thought it is not possible - or i have no idea how to interpret it.
> can3.gam <- gam(can>0~s(be)+s(crr)+s(ch)+s(home), family = 'binomial')
> summary(can3.gam)
Family: binomial
Link function: logit
Formula:
can> 0 ~ s(be) + s(crr) + s(ch) + s(home)
