  "Description": "Provides semiparametric smooth-coefficient stochastic\nfrontier analysis following Sun and Kumbhakar (2013)\n<doi:10.1016/j.econlet.2013.05.001> where the coefficients of\nthe parametric part vary smoothly with a set of nonparametric\nvariables. Inefficiency term is allowed to depend on a set of\ndeterminants through heteroskedasticity. Smooth coefficients\nare estimated using nonparametric regression and the remaining\nfrontier parameters are estimated by maximum likelihood.\nTechnical efficiency and inefficiency are computed using the\nBattese and Coelli (1988) <doi:10.1016/0304-4076(88)90053-X>\nand Jondrow et al. (1982) <doi:10.1016/0304-4076(82)90004-5>\nmethods, respectively. Confidence intervals for technical\nefficiency are computed using the approach of Horrace and\nSchmidt (1996) <doi:10.1007/BF00157044>.",
