abstract: 'Two-step and maximum likelihood estimation of Heckman-type sample selection
  models: standard sample selection models (Tobit-2), endogenous switching regression
  models (Tobit-5), sample selection models with binary dependent outcome variable,
  interval regression with sample selection (only ML estimation), and endogenous treatment
  effects models. These methods are described in the three vignettes that are included
  in this package and in econometric textbooks such as Greene (2011, Econometric Analysis,
  7th edition, Pearson).'
