  "Description": "Flexible stochastic tree ensemble software. Robust\nimplementations of Bayesian Additive Regression Trees (BART)\n(Chipman, George, McCulloch (2010) <doi:10.1214/09-AOAS285>)\nfor supervised learning and Bayesian Causal Forests (BCF)\n(Hahn, Murray, Carvalho (2020) <doi:10.1214/19-BA1195>) for\ncausal inference. Enables model serialization and parallel\nsampling and provides a low-level interface for custom\nstochastic forest samplers. Includes the grow-from-root\nalgorithm for accelerated forest sampling (He and Hahn (2021)\n<doi:10.1080/01621459.2021.1942012>), a log-linear leaf model\nfor forest-based heteroskedasticity (Murray (2020)\n<doi:10.1080/01621459.2020.1813587>), and the cloglog BART\nmodel of Alam and Linero (2025) <doi:10.48550/arXiv.2502.00606>\nfor ordinal outcomes.",
