mediation: Causal Mediation Analysis

We implement parametric and non parametric mediation analysis. This package performs the methods and suggestions in Imai, Keele and Yamamoto (2010) <doi:10.1214/10-STS321>, Imai, Keele and Tingley (2010) <doi:10.1037/a0020761>, Imai, Tingley and Yamamoto (2013) <doi:10.1111/j.1467-985X.2012.01032.x>, and Imai and Yamamoto (2013) <doi:10.1093/pan/mps040>. In addition to the estimation of causal mediation effects, the software also allows researchers to conduct sensitivity analysis for certain parametric models.
