PrivATE is a novel machine learning framework for computing confidence intervals (CIs) for the average treatment effect (ATE) under differential privacy.
The framework focuses on deriving valid privacy-preserving CIs for the ATE from observational data in sensitive settings such as medicine.
PrivATE consists of three steps: estimating a differentially private ATE, estimating the differentially private variance, and constructing CIs while considering uncertainty from both estimation and privatization steps.
This framework is model agnostic, doubly robust, and ensures valid CIs, demonstrated through synthetic and real-world medical datasets, marking a significant advancement in valid CIs for ATE under differential privacy.
