      abstract = {This paper explains why computing the marginal effect of a  change in two variables is more complicated in nonlinear  models than in linear models. The command inteff computes  the correct marginal effect of a change in two interacted  variables for a logit or probit model, as well as the  correct standard errors. The inteff command graphs the  interaction effect and saves the results to allow further  investigation.},
