I have two questions:
1. You have an y as dependent and an y as independent variable. Is that
a typo, or are you adding lagged y?
2. In this case correct marginal effects has been used in different
ways in the literature. First, it can refer to not ignoring the square
or interaction terms. Second, it can refer to computing the average
marginal effects, instead of the marginal effect at average values of
the explanatory variables. Which do you mean?
