It's probably a good idea to not throw more than 12 tasks at the system
simultaneously, but if you're calling an exe via the shell, it's not
clear to me why you want to control everything from gretl (as opposed to
the shell itself).
If you want proper control from within gretl for multiprocessing,
perhaps you should look at the MPI setup (see the gretl + MPI guide
under the help menu).

Question about parallel processing using the shell
by Logan Kelly
Hello all,
I am using the launch command in a loop to call out to a processor intensive estimation routine ( I am calling an exe file). My system only has 12 processor cores, so is there a way to limit the number of simultaneous processes to 12? Or should I just let windows handle it. Here are the specs of my setup:
OS: Win 10 pro 64 bit
grelt: latest git as of 2019-06-16
ram: 32gb
CPU's: 2 x Hex-Core Intel Xeon
Cheers,
Logan
P.S. I apologize if this is too far off topic.

Good morning, I am trying to import a panel data variable from excel in which I have in the first row all the entities and in the first column all the dates. How can I do that?

Yes, thank you so much, Jack. It does the job as advertised.
I just want to show how this is done to my students. I learned a whole lot in the process.
A minor issue with the interface, however.
When I installed the package felogit, there was a dialog box that says:
“The package felogit can be attached to the gretl menus
as ‘/menubar/Model/LimdepModels/logit/Fixed-effects logit’ in the main window.
Do you want to do this?”
My response was yes, and yet, there is no such menu item showing up.
What might be the cause of this?
I’m on a MacBook Pro, OS X 10.11.6, with gretl version 2019c-git

Package KaoTest.gfn to be retired soon
by Sven Schreiber
Dear all,
especially those interested in panel cointegration analysis, the
KaoTest.gfn package has certain issues and will be removed from the
gretl package server soon. The author couldn't be reached to address
those issues.
The good news is that work is ongoing to start a new package for panel
cointegration testing. The plan is that it will offer more tests than
the KaoTest package.
Nevertheless, if you are a user of that package and need it for your
work please keep a local copy of it to be on the safe side.

Article on gretl
by Artur Tarassow
Hi all,
let me do some self-advertising, please: I've published an article
entitled "Practical Empirical Research Using gretl and hansl" in the
Australian Economic Review in their "student section". The journal is
hosted at the University of Melbourne. Some econometrics professors and
teachers were thinking of using gretl instead of (or jointly with) R or
Eviews back in 2017/18 -- not sure whether any decision has been made on
this already. But nevertheless, maybe the article is of interest to some
of you...
URL: https://onlinelibrary.wiley.com/doi/full/10.1111/1467-8462.12324
Data and replication files are available on my github repo (details can
be found in the paper).
Best,
Artur

Gretl GUI and Date of script files
by cruz.echevarria＠ehu.eus
Dear Gretl Community,
Please let me pose the following issue: the GUI does not seem to display the date on which script files were last modified. Am I right?
If I go to "File" -> "Script files" -> "User file...", then I just can see 3 columns: "Name", "Size" and "Modified". But the last column only shows time, but not date, which I think would be useful. Is this a problem with my machine (running under Windows)? Is this what it should be? Am I just looking at the wrong place?
Thanks in advance.
Regards,
Cruz

Function package bkw.gfn
by Sven Schreiber
Dear users of collinearity analyses,
the function package bkw.gfn by Lee Adkins is going to be retired soon.
The reason is that its functionality has been integrated into gretl
itself via the new 'bkw' command and 'bkw()' function. See the
documentation in gretl 2019b (excellent as always).
Please speak up if you need a little transition period. Apart from that,
you can of course always keep a local copy of the package for your own use.
cheers

command line syntax documentation
by Fred Engst
Hi Allin,
I noticed a line of code that I didn’t know was possible from your response earlier:
"ols lwage 0 log(wage) —simple”
I can’t seem to find reference to what is acceptable and what is not on the ols command line.
Here you’ve invoked a function on the command line, i.e. log(wage), not a existing series’ name.
Other transformation is also possible, such as ols y 0 y(-1 to 4) that I’ve noticed.
This raises a question about the nature of the indepvars in the ols documentation.
What other command line transformation that is possible without creating a new variable first?
Where are they documented?
Thanks in advance.
