37  Supported Models

marginaleffects effects supports 102 model types directly, and dozens more via the tidymodels and mlr3 frameworks. This table shows the list of directly supported model types. There are three main alternative software packages to compute such slopes (1) Stata’s margins command, (2) R’s margins::margins() function, and (3) R’s emmeans::emtrends() function. The test suite hosted on Github compares the numerical equivalence of results produced by marginaleffects::slopes() to those produced by all 3 alternative software packages:

• ✓: a green check means that the results of at least one model are equal to a reasonable tolerance.
• ✖: a red cross means that the results are not identical; extra caution is warranted.
• U: a grey U means that computing slopes for a model type is unsupported by alternative packages, but supported by marginaleffects.
• An empty cell means means that no comparison has been made yet.

I am eager to add support for new models. Feel free to file a request or submit code on Github.
