  Abstract

mediation is a publicly available R package that allows both parametric and nonparametric causal mediation analysis. It implements the methods and suggestions in Imai, Keele, and Yamamoto (2010) and Imai, Keele, and Tingley (2010). In addition to the estimation of causal mediation effects, the software allows researchers to conduct sensitivity analysis for certain parametric models. See also the Stata version.
