Importing data from Excel and Gnumeric
by Allin Cottrell
I have been testing gretl's spreadsheet data importers more thoroughly
than before, in the course of making gretl files for the data that
accompany the textbooks by G. S. Maddala, and Stock and Watson.
In the process I have discovered quite a few little bugs and
"misfeatures", so there will be several fixes in gretl 1.2.2.
Hopefully, this should make the importation of such data easier and
more reliable.
I am also working on improving gretl's built-in data spreadsheet; that
too will have several small fixes in the GTK 2 version (which is also
the one used on MS Windows).

ARMA, and new list mechanism
by Allin Cottrell
In response to Ignacio's point about the failure of ARMA estimation
when the X-12-ARIMA option is selected, I have prepared a variant of
the gretl 1.2.1 "generic" rpm that is more verbose: it should tell us
which particular file is not being read.
ftp://ricardo.ecn.wfu.edu/pub/gretl/gretl-1.2.1-2generic.i386.rpm
One other point: I have decided to switch the gretl-users list to GNU
Mailman rather than Majordomo, for ease of management. You don't have
to do anything, but note that there is a new web interface to the
list:

ARMA issues in gretl 1.2.1
by Allin Cottrell
I have tracked down the problem that Ignacio mentioned: failure to
produce arma results when using the X-12-ARIMA option. This was an
i18n issue (I forgot to reset LC_NUMERIC before trying to read numbers
out of the X-12-ARIMA output files, so it will fail if the decimal
point character is not '.'). Fixed in CVS.
Also in CVS, I have fixed/enhanced some things relating to the
printout of arma results:
* RTF output of arma models was broken, now fixed
* Moduli and frequencies of AR and MA roots are now printed
(in plain text, LaTeX and RTF)
I'll wait a little to see if other bugs surface, then release a 1.2.2
with these arma fixes.
