There was a bug in gretl 1.9.4 that (strangely) only seemed to be
triggered on Ubuntu. It's fixed in the current release, 1.9.5.

It's not a built-in command, but it's not very difficult. Suppose
you have a "treatment" variable x and a "response" variable y, and
you want to plot y against x, with the points distinguished by the
associated value of some discrete variable d. Then:
<script>
matrix dvals = values(d)
nd = rows(dvals)
list yd = null
loop i=1..nd
series y$i = (d == dvals[i]) ? y : NA
yd = yd y$i
endloop
gnuplot yd x --output=display # or whatever option
</script>

Gretl crashes under Ubuntu Natty 11.04
by Hugo Cohan
I cannot launch Gretl after I automatically upgraded Ubuntu to Natty (11.04). I first blamed Unity, but problem persists launching Ubuntu Classic.
message is cannot find .... /grtl2rc
Apparently, a segmentation problem.
Any suggestions?

GRETL versus Stata: Time Series
by Charles Koss
I have used Stata and GRETL for univariate and multivariate time
series analyses. And today decided to share my opinion with the
community. I have concluded that GRETL is a reliable software for time
series analyses while Stata capabilities are still in development. An
example, Stata can estimate Vector Error Correction Models, however,
it can not provide estimates of the standard errors for the IRF's.
Therefore, I can not recommend Stata fot this type of analysis whereas
the opposite is true for GRETL.
In Stata, some time series estimators are written by users and then
down the road, the company incorporates them in the core software. An
example, rolling command for rolling regression. Other examples of
this practice, cusum and prais commands.
So, I would like to know some papers that compare the time series
capabilities of Stata and GRETL in order to have a better
understanding of the two softwares. Any help is appreciated.
Thank you,
Charles

updating gretl on OS X
by Allin Cottrell
I posted earlier some links to discussions of problems that OS X
users are having updating various apps. Here's a further thought
after digesting what I've read.
I believe this is an OS X bug, pure and simple. The point seems
to be that if an app defines certain files within its package as
read-only, then -- even after the user has authenticated him or
herself in response to a prompt from the OS -- updating the
package will fail. This despite the fact that the same user is
able to blow the whole currently-installed package away with no
problem. That's just inconsistent.
The gretl package contains various files marked as read-only, and
I'm not going to change that. For example, it's natural that as an
ordinary user you're not allowed to change the data files from the
Ramanathan textbook (though you're welcome to save changed
versions under another name).
In earlier versions of OS X this wasn't a problem: the same rights
that allowed you to delete the entire gretl installation also
allowed you to overwrite that installation with a new version.
Apple needs to get its act together with regard to the Darwin
equivalent of "sudo" operations on Linux.
I don't mind putting a note on the web page for gretl on OS X
alerting users to the fact that they may have to delete their
previous gretl installation before updating to a new version, but
that's as far as I'm willing to go to cater to broken behavior of
the OS.

That matches my own (recent) experience with OS X, though I'm
pretty sure there was a time when didn't get that "items are
blocked" message.

Yes, on the face of it, it looks as if the Finder is confused over

Well, it's what OS X now seems to do (at least part of the time).
The gretl installer hasn't changed; the behavior of OS X has. If
you can figure out how exactly OS X has changed in this respect
(e.g. via google) perhaps we can find a workaround.
