Hi,

I have fitted a model using a glm() approach and using a gls() approach
(but without correcting for spatially autocorrelated errors).  I have
noticed that although these models are the same (as they should be), the
AIC value differs between glm() and gls(). Can anyone tell me why they
differ?

Thanks,
Geertje
