Re: [Gretl-users] Gretl-users Digest, Vol 68, Issue 7 Gretl use on tablets
by Garry Stamm
Gentlemen
I use Gretl in professional work (although not a retired economist) and find it
extremely useful.First I just want to thank all of you that contribute so much
to making such a fabulous tool available. (It has forcibly extended my working
life.)
The topic of Gretl on a tablet is an interesting one and will become more so as
tablets are better married to keyboards and other input devices.
A quick suggestion:
QNX, which is now the core of the Blackberry tablet, and is being moved into
position to be the core OS of their phones has a high degree of compatibility
with linux/unix and uses a real time approach. Anyone with the skills (that I
unfortunately lack) can use the dingleberry program to open the core operating
system on the Blackberry tablet. Those with the system administration skills can
attempt to compile Gretl in the blackberry tablet. It should not prove too
difficult to do, no more than keeping it going on Ubuntu or Fedora, for example.
Although ipad with its similar unix-based os has the clear edge on consumer
favour at the moment, -- and a migration to that platform is clearly called
for, the Blackberry and android driven tablets are also out there and available
to a much wider set of international users.
regards

Re: [Gretl-users] GRETL users stackexchange site for more accessible exchange of knowledge
by Logan Kelly
Hello Gretl uses,
I am new to Gretl and would like to provide a gentle critique from the perspective of a new user. I have been using Gretl for about two months and have just completed the econometrics of my first project done exclusively using Gretl. Gretl has several strengths that make it one of the best econometric packages (commercial or open source) available:
1. Capabilities. At least in the realm of time series analysis (I do little with cross-section or panel), Gretl dominates competitors like Eviews or Stata
2. Ease of use. The scripting language, Hansel, is very intuitive for anyone with any programing knowledge. And much, much easier to master than that of Stata of Eviews. The language just makes sense.
3. Support. The responsiveness and helpfulness of users on the user listserv is incredible (second to none).
4. Access to the C source code.
As a new user, though, the greatest area for improvement is the documentation. As I have been learning the software, I have found that I have been forced to ask what seem to me to be pretty routine question. All of which have received prompt and helpful responses. But I still have the sense that I am taking other uses valuable time to answer question that have probably already been asked. Searching the listserv archives is a good starting point, but I have found finding the answer to my question, s.t. the answer is relevant to the current release of the software, difficult.
That said, the main Gretl developer are already preforming supper human feats of work by developing the software, answering question and writing documentation. Which is why I have found Trevor's suggestion of developing a stackexchange site so appealing. I am not yet capable of providing direct support of the software like the developers can, but I can help to create the a new FAQ that is more accessible for new users.
The bottom line is that I am sold on Gretl. I plan to use it going forward in both my teaching and research, and if I can help with the project, I am willing and I think there are a number of others who are too.

Subject: [Gretl-users] GRETL users stackexchange site for more accessible exchange of knowledge
Hi gretl users,
In my Aug 22, 2012 post (here: http://lists.wfu.edu/pipermail/gretl-users/2012-August/007948.html) I suggested that we look into switching to a format like stackexchange.com, where users can ask questions and the best answers get sorted to the top for later users to easily find information they're looking for. For a great example of a thriving stackexchange community, check out http://tex.stackexchange.com.
The thread died out pretty fast, but I am hoping maybe that's because everyone is busy and didn't want to through the legwork of setting up a stackexchange site. It turns out that it's extremely easy, so I did it myself.
You can visit it here: http://area51.stackexchange.com/proposals/43782/gretl?referrer=H784Ua9YLH...
The site will remain in this "area 51" limbo stage until it reaches 60 followers and 40 questions with a score of 10 or more. So when you visit the site, be sure to log in (you can use a Google, Yahoo, or any OpenID login) and click "follow" on the left-hand side. I know there are many more than 60 people out there using GRETL, so let's get the word out and soon we too will have a thriving Q&A community.
I took the liberty of posting a few recent questions from the mailing list so you can see how it works. Keep in mind the example questions are only question *titles*. Real questions could include long descriptions, example code, images, links, etc. You can also post example questions of the sort you'd like to see discussed on the site.
I really think this is a valuable direction to take this knowledge community, and I hope you agree. See you there!

Exporting *.gdt without losing data labels
by Arne Rogde Gramstad
Hello.
I was wondering if it is any way to export a Gretl dataset file (*.gdt)
to STATA without losing the data labels (as happens when exporting to CSV).

How to reference a separate time observations for a given time series in gretl?
by huugh＠centrum.cz
Hi,
is there a way how to reference a separate time observations for a given time series in gretl?
For example, if I wish to compute a "recession" dummy, i.e. an indicator with 1, if in the two last periods there were negative growth rates and 0 otherwise?
E.g. let's have this time series called X (below is some data, with the obs. number and growth rate)
Obs. no X ln(X)-ln(X(-1))
1 34296
2 30383 -0.121145488
3 28899 -0.050076249
4 27669 -0.04349434
5 26303 -0.050629652
6 26206 -0.003694609
7 26687 0.018188163
8 26424 -0.009903867
9 25458 -0.037242653
10 23749 -0.069489611
11 24709 0.039627125
12 25151 0.017730107
13 24431 -0.029044839
14 25740 0.052193384

20 24407 -0.050063383
21 25618 0.048425253
What command would generate the values of 1 for periods with two consequtive negative values in series? I.e. I would get this series:
n/a
n/a
1

Help on compiling gretl on ubuntu 10.04 Lucid Lynx
by yinung＠Gmail
Dear all,
I would like to build gretl from cvs as I did before but I failed. The
error message got after I do
./configure --enable-build-doc
were:
Please install libcurl and then reconfigure gretl.
libcurl is available from http://curl.haxx.se/libcurl/
I noticed that the gretl changelog mentioned that " Switch to using libcurl
for HTTP transaction support..."
I checked my ubuntu and found there were libcurl3 installed. I also went to
"http://curl.haxx.se/libcurl/" to download and install
"curl_7.19.7-1ubuntu1.1_amd64.deb." I still got the same error messages....
...
checking for FFTW... yes
checking for CURL... no
checking for GLIB... yes
checking for GTK... yes
It seems that curl is not found. Is there required versions for curl? Or
anything I am doing wrong?
Please help and thanks.
