Re: [Gretl-users] gretl work in progress (was Re: gmm)
Allin,
I'm revising the paper that I asked you to read a bit earlier, for
resubmission to JAE. Mackinnon wanted a quite different paper than the
one that I had drafted. I'm not sure that I can do what he wants. One of
my points is that GRETL has grown significantly even in the 3 - 4 years
since the previous review article. I cite expanded time series
capabilities and Tobit as examples. Also, I stress that GRETL, unlike
most student versions of software, allows students to learn about batch
processing, which will be important in hands-on work.
This note regards GRETL's growth. Would it be appropriate to add a
paragraph or two that relate directions in which GRETL is growing,
borrowing from your 18 January list-serve message?
Thanks for suggestions,
Wilson

I might just add a hint or two at what's going on (I agree, this is
exciting).
* We're adding a general facility for defining and manipulating
matrices. This is fairly well advanced but needs more testing. At
present we have most of the standard matrix operators and functions
implemented, using a syntax much like ox. People using gretl CVS can
read about this in the new manual chapter file, matrices.tex.
* We're also adding a general facility for "farming out" tasks from
gretl to other programs that offer functionality not (yet) available
in gretl. We already do that to some extent with x12arima and
tramo/seats, but Jack has developed a more general, elegant and
efficient mechanism that will allow gretl to exchange binary
information with external programs. Ox is the primary target at
present, but R is also a good candidate.
In combination, these facilities will greatly increase the
opportunities for people to write functions (in gretl script, not C)
that extend gretl's capabilites.
I'm also working (though this is at an early stage) on a gui interface
to such "add-on functions". The idea is you could download these from
some repository, then open up a gui window showing what functions are
available (and who wrote them, and what their purpose is), with the
option of loading any functions of interest into gretl's workspace,
where they could be used in scripts or at the gretl console. Perhaps
these add-on functions could even attach themselves at appropriate
positions in the gretl menu structure, and hence become directly
accessible via point-and-click.
