Supports models fitted with 'XGBoost', 'LightGBM', and 'CatBoost', with optimized backend-specific implementations and cached tree summaries suitable for large-scale problems. Multiple visualization tools are included for interpreting and communicating feature contributions. The methodology is described in Jiang, Zhang, and Zhang (2025) . Optional 'CatBoost' support uses the R package 'catboost', which is not distributed on CRAN; installation instructions and released binaries are provided by the CatBoost project at . authors: - family-names: He given-names: Steven email: hess1@uci.edu - family-names: Jiang given-names: Zhongli email: zhongli.jiang.stats@gmail.com - family-names: Zhang given-names: Dabao email: zdb969@hs.uci.edu repository: https://catstats.r-universe.dev repository-code: https://github.com/catstats/Q-SHAP_R commit: 0d56323cdb958aae2092f35ca511f9b14482cca1 url: https://github.com/catstats/Q-SHAP_R date-released: '2026-05-03' contact: - family-names: Jiang given-names: Zhongli email: zhongli.jiang.stats@gmail.com
