yes meta- frontier or MF model. The MF model is defined by Battese et al (2004) as a deterministic parametric frontier of specific functional form (e.g., Cobb Douglas or Translog) such that the predicted value for the MF is larger than or equal to the predicted value from the stochastic frontier for all firms and groups.
