years ago, I modified the stepAIC script from the MASS package to use
AICc. If and when I get time for this again, I plan to redo it using a
more complete Bayesian analysis.
However, if you want to use AICc,
Hi,
I'm fitting poisson regression models to counts of birds in

I do this in a stepwise way, using the stepAIC function. However the
resulting models appear to be overparametrized, since too much
variables were included.
