heckmanGE: Estimation and Inference for Heckman Selection Models with
Cluster-Robust Variance
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: <https://www.jstor.org/stable/27164235>). The package also offers 
  cluster-robust inference with sandwich estimators, and tools for handling issues 
  related to eigenvalues in covariance matrices.
