Contains routines for the deterministic metafrontier envelope of O'Donnell et al. (2008) <doi:10.1007/s00181-007-0119-4> via linear and quadratic programming, and the stochastic metafrontier of Huang et al. (2014) <doi:10.1007/s11123-014-0402-2>. Also supports latent class stochastic metafrontier analysis and sample selection correction stochastic metafrontier models. Depends on the 'sfaR' package by Dakpo et al. (2023) <https://CRAN.R-project.org/package=sfaR>.https://github.com/r-universe/sulmanolieko/actions/runs/29370257666Tue, 14 Jul 2026 21:24:18 GMTsmfa1.0.1successhttps://sulmanolieko.r-universe.devhttps://github.com/sulmanolieko/smfaefficiency-extraction.Rmdefficiency-extraction.htmlExtracting Efficiencies and MTRs2026-03-12 10:21:522026-07-14 20:14:53getting-started.Rmdgetting-started.htmlGetting Started with smfa2026-03-12 10:21:522026-07-14 20:14:53sfalcmcross-metafrontier.Rmdsfalcmcross-metafrontier.htmlLatent Class SFA Metafrontier (groupType = "sfalcmcross")2026-03-12 10:21:522026-07-14 20:14:53sfaselectioncross-metafrontier.Rmdsfaselectioncross-metafrontier.htmlSample Selection SFA Metafrontier (groupType = "sfaselectioncross")2026-03-12 10:21:522026-07-14 21:24:18sfacross-metafrontier.Rmdsfacross-metafrontier.htmlStandard SFA Metafrontier (groupType = "sfacross")2026-03-12 10:21:522026-07-14 21:24:18
