Mediation Analysis in Causal Inference

Extending effects defined through mediation (e.g., direct effects) to stochastic interventions and intermediate confounders.

Causal Effects of Stochastic Interventions

Estimation and inference for causal effects based on stochastic treatment regimes, under two-phase sampling, in mediation settings, and for variable importance analysis.
