metafrontieR 1.0.0

Initial CRAN release

  • First public release of metafrontieR.
  • Implements stochastic and deterministic metafrontier analysis for productivity and performance benchmarking across firms operating under different technologies.
  • Supports three group-frontier types via ‘sfaR’:
    • Standard SFA (sfacross)
    • Latent class SFA (sfalcmcross)
    • Sample-selection-corrected SFA (sfaselectioncross)
  • Three metafrontier estimation methods:
    • Linear programming (LP) deterministic envelope
    • Quadratic programming (QP) deterministic envelope
    • Second-stage stochastic frontier (Huang et al. 2014; O’Donnell et al. 2008)
  • Full efficiency outputs via efficiencies(): group TE (JLMS and BC), metafrontier TE, and metatechnology ratios (MTR).
  • Five vignettes illustrating each major use case.
