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 (<doi:10.1002/sim.7426>) and natural (<doi:10.1515/jci-2016-0006>) direct and indirect effects. Estimation uses the parametric g-formula (<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.

Causal Mediation Analysis with causalMed
Introduction | The two estimands | Requirements | Survival data | Single mediator: interventional effects | The interventions | The decomposition | Permutation averaging: n_vw | Other exposure regimes | Multiple mediators: the Yamamuro et al. (2021) simulation | Censoring | Absorbing states with subset | Bootstrap confidence intervals | Natural effects | Targeted estimation | References

causalMed and gfoRmula: A Comparative Overview
Overview | Shared foundation | What gfoRmula offers that causalMed does not | What causalMed adds: mediation | Interfaces | Side-by-side estimates | Data preparation | Example 1: Binary end-of-follow-up outcome | Example 2: Survival (time-to-event) outcome | Example 3: Dynamic intervention | Larger Monte Carlo sample | References
