A few weeks ago, I have uploaded a new R package "frontier" for Stochastic
Frontier Analysis (SFA)  to CRAN . It includes the FORTRAN code of Tim
Coelli's  software "Frontier 4.1" . Hence, the R package "frontier"
should have the same capabilities as "Frontier 4.1", i.e. 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)  and a model
specification in which the firm effects are directly influenced by a number
of variables (Battese and Coelli, 1995) .
The functions "front41WriteInput" and "front41ReadOutput" for creating
input files for and reading output files of "Frontier 4.1" will be moved from
the "micEcon" package  to the "frontier" package within a short time.
The "frontier" package is developed on R-Forge . All useRs and
developeRs are invited to contribute to this package.
