%description
Implements metafrontier production function models for estimating
technical efficiencies and technology gaps for groups of firms that face
different restrictions of a common underlying metatechnology
(group-specific technologies in the sense of Battese, Rao, and O'Donnell,
2004). Supports both stochastic frontier analysis (SFA) and data
envelopment analysis (DEA) based metafrontiers. Includes the deterministic
metafrontier of Battese, Rao, and O'Donnell (2004)
<doi:10.1023/B:PROD.0000012454.06094.29>, the stochastic metafrontier of
Huang, Huang, and Liu (2014) <doi:10.1007/s11123-014-0402-2>, and the
metafrontier Malmquist productivity index of O'Donnell, Rao, and Battese
(2008) <doi:10.1007/s00181-007-0119-4>. The deterministic metafrontier can
be identified by either the minimum sum of absolute deviations (LP) or the
minimum sum of squared deviations (QP) criterion. Additional features
include panel SFA with time-varying inefficiency, bootstrap confidence
intervals for technology gap ratios, a DEA poolability permutation test,
latent class metafrontier estimation via the EM algorithm, Murphy-Topel
corrected standard errors, convergence diagnostics, import of pre-fitted
models from external estimation engines ('sfaR', 'frontier',
'Benchmarking'), and 'ggplot2' visualisation methods.
