dummify with list and script output window
by Pindar
Hi,
I noticed that between command and function is a major difference:
dummify dList -> works with a list
dummify(dList, NA) -> only one series accepted
In terms of the script output window I think what would be a
nice-to-have is the option that as soon as output is added the window
goes to the front.
This is not always intended and could be annoying, but sometimes
(especially if one likes the eval command) this would come in handy.
Cheers

Problems running Gretl on Mac OSX Lion
by Mirko Weber
Hello Community,
i have some problems running Gretl on Mac OSX Lion. I have Intel i5 Macbook Pro from 2011 and I followed all the steps on
http://gretl.sourceforge.net/mac-intel.html
including the installation of GTK+ Framework and the the steps given in the README.pdf. When i wanted to open Gretl in the normal Applications Folder it gives me the Message:
"You can´t open the Program "Gretl", because it is not supported by your type of Mac"
(Because I´m from Germany i had to translate the error message, so it might look slightly different on english)
I definitely downloaded the gretl version for intel macs and the right GTK+ Framework (I did it several times to be sure as it did not work) and as my Os is Lion, X11 was already installed. So i followed the Trouble-Shooting section in the README.pdf an executed Gretl manually via X11 xterm. Then this error-message appears:
dyld: Library not loaded: @executable_path/../lib/libgmp.3.dylib
Referenced from: /Applications/Gretl.app/Contents/Resources/bin/gretl_x11
Reason: no suitable image found. Did find:
/Applications/Gretl.app/Contents/Resources/bin/../lib/libgmp.3.dylib: file too short
/Applications/Gretl.app/Contents/Resources/bin/../lib/libgmp.3.dylib: file too short
Trace/BPT trap: 5
I tried to find answers in the previously discussed problems on running Gretl on mac, but i did´t find anything that worked for me!
Thanks for your answers and greetings

gnuplot issue with histogram
by artur tarassow
Hi gretl-list members,
actually this is a gnuplot issue but I thought that somebody may help me
with this.
I set up a function (see file attached) to plot some barplots but it does
not work as it is planned. I have a matrix
A = { 1999, 2.2, 3, 2 ; 2000, 2.8, 1.1, 2 ; 2001, 3, 2.2, 2; 2002, 2.2, 3,
2 } for which I want to plot columns 2 to 4 for each year but at the moment
only column 2 is plotted.
I suspect to the problem being with the following line in the code:
printf "plot '-' using 2:xtic(1) ti col, '' u 3 ti col, '' u 4 ti col\n"
I tried different ways but for some reason columns 3 and 4 don't appear .
Does anybody have an idea what's wrong with the code here? I am using
current CVS on windows.
Best,
Artur

I am a new user to gretl system
by Nabil Brandl
I tried Gretl system and I impressed for the results. I compared Gretl
system with SAS statistics package. I used SAS in 30 years and I want to
learn how make my own gretl program. I used SAS for scientific purpose and I
intended to use gretl system in scientific purpose. I did experiments in
using image analysis to estimate animal weight, using the relationship
between weight and body area from above. I run my data by gretl system and
found the same results as in SAS system.
Best regards and keep inc touch

Hi gretl prorammers,
despite the fact that I activated "set warning off", I receive the message
"No observations would be left!" after selecting an obviously non-existing
panel data sample.
Actually I would expect no message at all in this case. Is this intended,
or a 'bug'? It is a bit annoying as it appears in the txt-output using the
'outfile' command.
Best,
Artur

Excellent stuff - I thought I was on the right track! Nice to be able to
deploy some correct logic for once.
Thanks for pulling me up on not reading the documentation, but in my
defence: (a) I've only just installed -gretl-; (b) it's Christmas, so I've
not had much of a chance to peruse what is a very large users' guide; and
(c) I did look at the program help on restrictions (although clearly
they're not as comprehensive as that laid out in the guide).
If I may, I had another quick query about panel-corrected standard errors.
I'm delighted you've included them in -gretl-, but I've had no luck in
fitting any fixed-effect models with PCSEs (N=47, T=36, NT=795, with ten X
variables; all bar the first and last of the time dummies were included;
there was no lagged dependent variable). Every time I do, the model does
run, but with the message "Could not compute Beck-Katz errors". I'm sure
the reasons for not doing so are valid, but no reason was given at all. Why
is this? Also, which standard errors are reported instead?
Thanks again. :)

gretl and R crash
by Pindar
Hi there,
in order to perform a cluster analysis I tried the R connection with
'C:\Program Files\R\R-2.15.2\bin\i386\Rgui.exe'
and
'C:\Program Files\R\R-2.15.2\bin\i386\R.dll'
gretl does send the data set, however when running
'end foreign' gretl crashes with the message: "Fatal error: unable to
open the base package"!
I'm using the snapshot on Windows 8.

on the summary command
by Pindar
Hi,
while working on my MANOVA function I realized that the build in command
'summary' could be easily used for (at least) some
steps for this analysis if it's output would be accessible. At the
moment it's not, right?
For this purpose something like
'mySummary <- summary varlist --by=series' should work. At the moment
'mySummary' is saved, but nowhere visible.
The --by=series could be improved by --by=varlist. However, looping
through 'summary' would do also.
I also now looked up the function packages and found 'meansby' and
'summary_xy'.
I should have take a look earlier :-) Well, why not integrating such
useful functions into the 'standard' commands/functions?
Best
