Maximum Likelihood Estimation of
Stochastic Frontier Production and Cost Functions.
Two specifications are available:
the error components specification with time-varying efficiencies
(Battese and Coelli, 1992, <doi:10.1007/BF00158774>)
and a model specification in which the firm effects are directly
influenced by a number of variables (Battese and Coelli, 1995,
<doi:10.1007/BF01205442>).
