te( ) interactions and AIC model selection with GAM
Simon, could you clarify this paragraph. We are submitting to a psychology journal and I am certain they will be asking us about why it is still ok to use AIC for non-nested models. Thanks. Will Shadish

For AIC model comparison, the usual advice applies that although the comparisons are a bit more reliable for nested models (since then some of the AIC approximations errors are the same in both cases, and cancel in the comparison), it is still ok to use AIC for non-nested models (i.e. it is *not* like most hypothesis testing where everything falls apart if you don't have nesting). best, Simon
