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.}, url = {http://ageconsearch.umn.edu/record/116235}, doi = {https://doi.org/10.22004/ag.econ.116235}, }
