Traditional solutions require\ninstrumental variables (IVs), which are often difficult to find\nand validate. This package provides flexible, alternative\nIV-free methods using copulas, as described in the practical\nguide to endogeneity correction using copulas (Yi Qian, Tony\nKoschmann, and Hui Xie 2025) .\nThe current version implements the two-stage copula endogeneity\ncorrection (2sCOPE) method to fit models with continuous\nendogenous regressors and both continuous and discrete\nexogenous regressors, as described in Fan Yang, Yi Qian, and\nHui Xie (2024) . Using this\nmethod, users can address regressor endogeneity problems in\nnonexperimental data without requiring IVs.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "LazyData": "true",
