Deriving Posterior Distributionsresentation of ..(..,..) is missing. This is exactly the case with a DEA estimated frontier. So parameter estimation based on analytical evaluation of this likelihood in applied work (with unknown frontier) is impossible.

On the other hand we would never observe zero efficiency with regard to any of the outputs (i.e. .(.. = 0) = 0 for all . = 1... .). Neither of the two assumptions seems particularly far
