causalMed: Parametric G-Formula for Longitudinal Mediation and Total Effects

Causal mediation analysis for longitudinal data with time-varying exposures, mediators and confounders, covering both interventional (Lin et al. (2017) <doi:10.1002/sim.7426>) and natural (Zheng and van der Laan (2017) <doi:10.1515/jci-2016-0006>) direct and indirect effects. Estimation uses the parametric g-formula (Robins (1986) <doi:10.1016/0270-0255(86)90088-6>), which is also exposed directly so that counterfactual means or risks can be estimated under static, dynamic or time-varying hypothetical interventions.
