Package: heckmanGE Title: Estimation and Inference for Heckman Selection Models with Cluster-Robust Variance Version: 1.0.0 Date: 2024-10-02 Authors@R: c(person("Bastos", "Fernando de Souza", , "fernando.bastos@ufv.br", role = c("aut", "cre"), comment = c(ORCID = "0000-0003-1503-4599")), person("Barbosa", "Rogério Jerônimo", , "rogerio.barbosa@iesp.uerj.br", role = "aut", comment = c(ORCID = "0000-0002-6796-4547")), person("Prates", "Marcos Oliveira", , "marcosop@est.ufmg.br", role = "aut", comment = c(ORCID = "0000-0001-8077-4898")) ) Description: Tools for the estimation of Heckman selection models with robust variance-covariance matrices. It includes functions for computing the bread and meat matrices, as well as clustered standard errors for generalized Heckman models, see Fernando de Souza Bastos and Wagner Barreto-Souza and Marc G. Genton (2022, ISSN: ). The package also offers cluster-robust inference with sandwich estimators, and tools for handling issues related to eigenvalues in covariance matrices.
