Recursive partitioning for heterogeneous causal effects, Susan Athey, Guido W. Imbens, 2016Proceedings of the National Academy of Sciences, Vol. 113 (National Academy of Sciences)DOI: 10.1073/pnas.1510489113 - This foundational paper introduces the Causal Forest algorithm, outlining the concepts of honest estimation and causal splitting criteria for estimating heterogeneous treatment effects.
Generalized Random Forests, Susan Athey, Julie Tibshirani, Stefan Wager, 2019The Annals of Statistics, Vol. 47DOI: 10.1214/18-AOS1709 - This work presents the Generalized Random Forests (GRF) framework, extending Causal Forests to a wider class of local parameters and providing theoretical properties for estimation and inference.
grf: Generalized Random Forests, Julie Tibshirani, Susan Athey, Erik Sverdrup, Stefan Wager, 2024 (CRAN)DOI: 10.32614/CRAN.package.grf - The official R package implementation of Generalized Random Forests, which includes Causal Forests. It provides practical tools for applying these methods and accessing their functionalities.
