%description
Nonparametric efficiency measurement and statistical inference via DEA
type estimators (see Färe, Grosskopf, and Lovell (1994)
<doi:10.1017/CBO9780511551710>, Kneip, Simar, and Wilson (2008)
<doi:10.1017/S0266466608080651> and Badunenko and Mozharovskyi (2020)
<doi:10.1080/01605682.2019.1599778>) as well as Stochastic Frontier
estimators for both cross-sectional data and 1st, 2nd, and 4th generation
models for panel data (see Kumbhakar and Lovell (2003)
<doi:10.1017/CBO9781139174411>, Badunenko and Kumbhakar (2016)
<doi:10.1016/j.ejor.2016.04.049>). The stochastic frontier estimators can
handle both half-normal and truncated normal models with conditional mean
and heteroskedasticity. The marginal effects of determinants can be
obtained.
