I know this sounds like a plug and one shouldn't brag about his own work, but I'd like to say a couple of words about the new package called "frontier" that I put together for performing stochastic frontier analysis and is now available on the gretl server.

This package gives you, in practice, the combination of the two old packages "sfa_mod" and "sfa_eff" by Gordon Hughes,

Hi, what about this sfa_eff package, currently we only have sfa_mod on the server I think?
Apart from that, thanks for the development in this area!

cheers,
