It computes two- and three-way interaction effects — via partial derivatives or first differences — for fitted regression models, with delta-method standard errors.</p> <p>Built as a thin wrapper around <a href="https://marginaleffects.com" target="_blank" rel="noopener">marginaleffects</a>, it supports arbitrary variance–covariance specifications (<code>&quot;HC3&quot;</code>, clustered, or a user-supplied sandwich matrix), which propagate through to the final interaction-effect standard errors.</p> <pre><code># install.packages(&quot;remotes&quot;) remotes::install_github(&quot;jespernwulff/ginteff&quot;) </code></pre>
