abstract: Maximum-likelihood estimation of the spatial autoregressive stochastic frontier
  model with individual fixed effects (removed by first differencing) and endogenous
  regressors handled through a Gaussian control function, as in Giannini (2025) <https://doi.org/10.1080/17421772.2024.2414962>.
  Returns coefficient estimates and standard errors, spatially-corrected technical
  (in)efficiency scores, and direct, indirect and total marginal impacts. Depends
  only on base R.
