Supports both\nstochastic frontier analysis (SFA) and data envelopment\nanalysis (DEA) based metafrontiers. Includes the deterministic\nmetafrontier of Battese, Rao, and O'Donnell (2004)\n, the stochastic\nmetafrontier of Huang, Huang, and Liu (2014)\n, and the metafrontier Malmquist\nproductivity index of O'Donnell, Rao, and Battese (2008)\n. The deterministic metafrontier\ncan be identified by either the minimum sum of absolute\ndeviations (LP) or the minimum sum of squared deviations (QP)\ncriterion. Group frontiers can be production or cost frontiers,\ncorrected for sample selection following Greene (2010)\n, or spatial-autoregressive\nstochastic frontiers. Transitive Fare-Primont and Lowe\nproductivity indexes (O'Donnell, 2012\n) are decomposed against group\ntechnologies and the metatechnology. Additional features\ninclude panel SFA with time-varying inefficiency, bootstrap\nconfidence intervals for technology gap ratios, a DEA\npoolability permutation test, latent class metafrontier\nestimation via the EM algorithm, Murphy-Topel corrected\nstandard errors, convergence diagnostics, import of pre-fitted\nmodels from external estimation engines ('sfaR', 'frontier',\n'Benchmarking'), and 'ggplot2' visualisation methods.", "License": "GPL (>= 3)", "Encoding": "UTF-8", "RoxygenNote": "7.3.3", "VignetteBuilder": "knitr", "URL":
