%description
In order to facilitate the adjustment of the sample selection models
existing in the literature, we created the 'ssmodels' package. Our package
allows the adjustment of the classic Heckman model (Heckman (1976),
Heckman (1979) <doi:10.2307/1912352>), and the estimation of the
parameters of this model via the maximum likelihood method and two-step
method, in addition to the adjustment of the Heckman-t models, introduced
in the literature by Marchenko and Genton (2012)
<doi:10.1080/01621459.2012.656011> and the Heckman-Skew model introduced
in the literature by Ogundimu and Hutton (2016) <doi:10.1111/sjos.12171>.
We also implemented functions to adjust the generalized version of the
Heckman model, introduced by Bastos, Barreto-Souza, and Genton (2021)
<doi:10.5705/ss.202021.0068>, that allows the inclusion of covariables to
the dispersion and correlation parameters and a function to adjust the
Heckman-BS model introduced by Bastos and Barreto-Souza (2020)
<doi:10.1080/02664763.2020.1780570> that uses the Birnbaum-Saunders
distribution as a joint distribution of the selection and primary
regression variables.
