Equivalent AIC values

Hello R-helpers. We have a question about AIC values. We ran several different GLMs (quadratic, interactions) and our lowest AIC values were the same for several different models. We don't know how to interpret this. Any thoughts? Thanks in advance.
Well, the work equally well according to AIC (which is one of so many different ways to compare models). If you use another criterion you will probably find a different solution. Hence use the model you prefer due to other facts than just those numbers. Uwe Ligges
