emmeans: Estimated Marginal Means, aka Least-Squares Means

Russell V. Lenth, Julia Piaskowski

Short summary

The 'emmeans' R package provides a unified framework for obtaining estimated marginal means (EMMs) and performing post-hoc analyses for a wide range of linear, generalized linear, and mixed models.

Abstract

Obtain estimated marginal means (EMMs) for many linear, generalized linear, and mixed models. Compute contrasts or linear functions of EMMs, trends, and comparisons of slopes. Plots and other displays. Least-squares means are discussed, and the term "estimated marginal means" is suggested, in Searle, Speed, and Milliken (1980) Population marginal means in the linear model: An alternative to least squares means, The American Statistician 34(4), 216-221 &lt;<a href="https://doi.org/10.1080%2F00031305.1980.10483031" target="_top">doi:10.1080/00031305.1980.10483031</a>&gt;.
