We decompose the ATE estimand as the difference between a pooled-ATE estimand that integrates RCT and RWD and a bias estimand that captures the conditional effect of RCT enrollment on the outcome.

Conformal prediction helps decision-makers quantify uncertainty in point predictions of outcomes, allowing for better risk management for actions.

We introduce efficient plug-in (EP) learning, a novel framework for the estimation of heterogeneous causal contrasts, such as the conditional average treatment effect and conditional relative risk.

For this reason, practitioners may resort to simpler models based on parametric or semiparametric assumptions.

We propose causal isotonic calibration, a novel nonparametric method for calibrating predictors of heterogeneous treatment effects.
