cran.r-project.orgmodelis an appropriate fitted-model object. Additional arguments to allEffects, predictorEffects and plot can be used to customize the resulting displays. The function effect can be employed to produce an effect display for a particular term in the model, or to which terms in the model are marginal.

opr.princeton.eduMarginal effect (ME) measures the effect on the conditional mean of y of a change in one of the regressors . In the linear regression model, the marginal effect equals the relevant slope coefficient. For non-linear models this is not the case and hence there are different methods for calculating marginal effects.

users.rowan.edu10. What is the marginal change in textbook price for each additional page? Marginal change is simply the slope of the regression line. Hence, the marginal change for our example is -0.111 dollars/page. In other words, the price of an introductory statistics textbook decreases by an average of $0.111 for each additional page.
