Mediation Analysis in Causal Inference

Investigations in estimating causal effects defined in the presence of mediation (e.g., natural direct effect), based on stochastic treatment regimes.

Causal Inference with Stochastic Interventions

Investigations in causal inference with stochastic treatment regimes, a flexible formalism more realistic than dynamic or deterministic treatment rules.
