Dear all,
I'm using a binomial distribution with a logit link function to fit a GAM
model. I have 2 questions about it.
First i am not sure if i've chosen the most adequate distribution. I don't have
presence/absence data (0/1) but I do have a rate which values vary between 0
and 1. This means the response variable is continuous even if within a limited
interval. Should i use binomial?
Secondly, in the numerical output i get negative values of UBRE score. I would
like to know if one should consider the lowest absolute value or the lowest
real value to select the best model.
Thank you in advance for your help.
Marina
