%description
Researchers across disciplines often face biased regression model
estimates due to endogenous regressors correlated with the error term.
Traditional solutions require instrumental variables (IVs), which are
often difficult to find and validate. This package provides flexible,
alternative IV-free methods using copulas, as described in the practical
guide to endogeneity correction using copulas (Yi Qian, Tony Koschmann,
and Hui Xie 2025) <doi:10.1177/00222429251410844>. The current version
implements the two-stage copula endogeneity correction (2sCOPE) method to
fit models with continuous endogenous regressors and both continuous and
discrete exogenous regressors, as described in Fan Yang, Yi Qian, and Hui
Xie (2024) <doi:10.1177/00222437241296453>. Using this method, users can
address regressor endogeneity problems in nonexperimental data without
requiring IVs.
