EconML aims to combine machine learning with econometrics to automate complex causal inference problems. EconML enables the estimation of heterogeneous treatment effects (HTE) – the impact of an intervention on an outcome, varying based on individual characteristics. The package implements state-of-the-art ML algorithms like random forests, boosting, lasso, and neural nets within a unified framework, preserving causal interpretation and often providing confidence intervals.
EconML offers flexibility in modeling effect heterogeneity using various machine learning techniques. It emphasizes maintaining causal interpretation and providing reliable inference results. The package provides a unified API for different techniques, simplifying their application. It focuses on handling observational data, making it practical for real-world scenarios where experimental data is limited.
