No. As the message says, NCDF.T has not been implemented.
I think we have had similar questions before about this error message. I wonder
if we should reword it? It is a typical case of confusion which arises from use
of the passive voice in English."... has not been implemented" implies that something should have been implemented. That raises the question: "by whom?". I think some users have misinterpreted this message to mean that they (the user) should have done something. Perhaps we should reword it to something like "This function is not available in this version of PSPP". I am reluctant to use the word "supported" like so many proprietary software vendors seem to throw around, because in PSPP (as in most proprietary software) absolutely *nothing* is "supported" unless one has taken out an explicit support contract. Also, perhaps we should update the manual. It is incorrect when the manual says "The following continuous distributions are available", when this one is not.
