Dear Jim This forum is about the R package "frontier" -- it is NOT about the stand-alone software "FRONTIER 4.1". Given that the R package "frontier" has several advantages over "FRONTIER 4.1" (see, e.g., http://frontier.r-forge.r-project.org/), I highly recommend that you use the R package "frontier" rather than "FRONTIER 4.1". Anyway, your estimation output indicates that the estimate of gamma is virtually zero so that all efficiency scores are all virtually one (fully efficient). Best regards, Arne |
