Marginal effects of main effects are often close enough to constant and they hardly ever switch signs. This is not true for marginal effects of interaction terms. I think of marginal effects as a linear model fitted on top of our non-linear model. Models are wrong, but as long as they are close enough, they can be useful. Average marginal effects for regular variables are often close enough so they can be useful. For interaction effects that linear model of the non-linear model just breaks down. -- Maarten -------------------------- Maarten L.
