abstract: Implements stochastic metafrontier analysis for productivity and performance
  benchmarking across firms operating under different technologies. Contains routines
  for the deterministic metafrontier envelope of O'Donnell et al. (2008) <https://doi.org/10.1007/s00181-007-0119-4>
  via linear and quadratic programming, and the stochastic metafrontier of Huang et
  al. (2014) <https://doi.org/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>.
