macc performs causal mediation analysis under confounding or correlated errors. This package includes a single level mediation model, a two-level mediation model and a three-level mediation model for data with hierarchical structure. Under the two/three-level mediation model, the correlation parameter is identifiable and estimated based on a hierarchical-likelihood or a two-stage method.
