⚠️There's a newer version (1.2-12) of this package.Take me there.
sampleSelection (version 1.2-6)
Sample Selection Models
Description
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).
