%description
Provides semiparametric smooth-coefficient stochastic frontier analysis
following Sun and Kumbhakar (2013) <doi:10.1016/j.econlet.2013.05.001>
where the coefficients of the parametric part vary smoothly with a set of
nonparametric variables. Inefficiency term is allowed to depend on a set
of determinants through heteroskedasticity. Smooth coefficients are
estimated using nonparametric regression and the remaining frontier
parameters are estimated by maximum likelihood. Technical efficiency and
inefficiency are computed using the Battese and Coelli (1988)
<doi:10.1016/0304-4076(88)90053-X> and Jondrow et al. (1982)
<doi:10.1016/0304-4076(82)90004-5> methods, respectively. Confidence
intervals for technical efficiency are computed using the approach of
Horrace and Schmidt (1996) <doi:10.1007/BF00157044>.
