...ilable: the error components specification with time-varying efficiencies (Battese and Coelli, 1992) [5] and a model specification in which the firm effects are directly influenced by a number of variables (Battese and Coelli, 1995) [6]. 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 [7] to the "frontier" package within a short time. The "frontier" package is developed on R-Forge [8]. All useRs and developeRs are...

Dear R users, I would like to inform you that everything of the "micEcon" package that is related to Stochastic Frontier Analysis (SFA) has been moved to the "frontier" package, because this is a more appropriate place for the functions "front41WriteInput", "front41ReadOutput", and "front41Est", and the corresponding (S3) methods. The data sets "riceProdPhil" and "Coelli" have been removed from the "micEcon" package, because they were already included in the "frontier" package (the latter is named "front41Da...

I need to estimate maximum tree crown radius and am looking for a package to prepare stochastic frontier models in R. I have not found any package references on Nabble R help, google, or R help. Any tips on a package for this? With regards, Aaron Trowbridge Researcher BV Research Centre Smithers B.C. -- View this message in context:
