Apparent Bug ...
by Fernando Fernandes Neto
Hi there,
I'm having problems while trying to execute the following command sequence:
matrix Q_S = {1, 1; 1, 1}
scalar beta_p = 0.9
matrix Q = beta_p * Q_s
The output is this:
Warning: generated non-finite values
And, when I check the Q Matrix, I find "Nan" in all elements. The output
should be 0.9 in all elements...
Is this a bug? Or am I missing something?
Thanks in advance,
Fernando

Cannot run Gretl 64 bit on Windows 7 64 bit
by Henrique Andrade
Dear Gretl Community,
I just had formatted my Windows 7 (64 bit) PC and now I cannot run Gretl
(64 bit) anymore. I am able to install the software but I crashes every
time I try to open it (by double-clicking). I'm running the debug mode but
it doesn't give any hints about the problem. Any help will be strongly
appreciated.
Best regards,
Henrique Andrade

how to feed efficiently Yahoo download function...
by guido giaume
Dear Sven
thanks for your time.
I am sorry if I was unclear.
My interest at the moment is tracking (and working with) my domestic
stock index (FTSEMIB).
The first thing is downloading and storing the rough data.
But - as you knows - sometimes the composition of the index changes.
So I have (at least) two ways to cover these changes.
a) [brute force] For every variation of the index I have to change
every single loop of my gretl scripts.
b) [more sophisticated] creating a "list" to be called by the gretl
script when it needed AND changing only once the "list" every time the
composition of the index changes.
Today I found this solution, but I am wondering if is optimal. So let
me change the question.
There is a better solution than
-------------
strings P = defarray("A2A.MI", "ANIM.MI", "ATL.MI", "AZM.MI",
"BMPS.MI")
# Open 10 days set
nulldata 10
# Time series
setobs 5 2016-07-01 --time-series
# call yahoo_get
include yahoo_get.gfn
# download
loop i = 1..nelem(P)
A=yahoo_full (P[i])
endloop
# store
store "/home/guido/gretl/prova_array.gdt"
-----------

how to feed efficiently Yahoo download function with a list of strings
by guido giaume
Dear All
I think "yahoo download" package is very nice and useful but
at the moment I use this function in a very inefficient way.
E.G.
-----------------------
loop foreach i A2A.MI ANIM.MI ATL.MI [cut]
A=yahoo_full("$i")
endloop
--------------------
If i want to download a long list of stocks should be better to use a
list, instead typing each ticker.
But when i read the 14th Chapter (named list) - which is very clear
also for a newbe in programming - I get confused because mostly speaks
about variables lists. And I was unable to extract some useful hint
from the 14.2 paragraph, which seems the right place to look for.
So again I ask your help.
By the way I found curious i was unable to donwload with that function
no less than 2 days. I mean, if I try to donwload only one day i can't.
Many thanks

by guido giaume
Dear All
thanks for all your suggestions and support.
Finally I build the 2016c release over a fresh installation 16.04.
Was tiresome, but everything works fine.
I dont have enough time and knowledge to dectect eventual problems
between ubuntu 16 and the 2016a.

Re: [Gretl-users] SVAR bootstrap output table etc.
by jayeryu
Thank you very much!
1. Adding 0 worked. I got the bootstrap output.
2. There is a red flag for the short and long run restrictions, though. I put the two restrictions simultaneously but the results are widely different from what my coauthor obtained from RATS and GAUSS.
The result from gretl shows a C matrix that looks like one that just superimposed short and long run matrices in a way that any 0 values in either of the two matrices replaced the relevant element of the C.
In addition, the bootstrap did not run adequately. Any advice would be greatly appreciated! Jay

Uh, you're right. There's an undocumented fourth parameter to SVAR_boot:
it's an optional boolean "quiet" flag, which defaults to 1.
Supplying a 0 as fourth parameter to SVAR_boot, as in
<hansl>
SVAR_boot(&Model, 1000, 0.95, 0)
</hansl>
should do the trick.
I'll update the documentation asap.

AFAIK, it should. Does the example script "BlQuah_w_sr.inp" (available in
the "Resources" directory) work for you?

Conflict between ubuntu 16.04 and gretl 2016a? - BE CAREFUL read before upgrading
by cociuba mihai
If you want to install Gretl from sources and you are familiar with the
terminal then use the following commands:
#git should already be install on your PC
#make a Gretl directory where you will download the sources
mkdir gretl-git
# change directory to gretl-git
cd gretl-git
#copy the sources
git clone git://git.code.sf.net/p/gretl/git gretl-git
#build the dependencies, but sometimes you will have to install the
dependencies one by one
sudo apt-get build-dep gretl
./configure --enable-build-doc --enable-openmp
make
make pdfdocs
sudo make install
#chck to see if Gretl runs
gretl
#OPTIONAL
#some dependencies
# curl si libgtk
sudo apt-get install libcurl4-openssl-dev && apt-get install
libgtksourceview2.0-dev
#json
sudo apt-get install libjson-glib-dev

Conflict between ubuntu 16.04 and gretl 2016a? - BE CAREFUL read before upgrading
by guido giaume
Dear all
two days ago i upgraded from 15.10 and immediatly i experienced a great
loss of performance. Loading a 8 Mega database taked more than 10
minutes. Computing was very slow.
Instead the speed of loading of the same database in another pc less
powerful is very fast.
Initially i thought the reason was an upgrade failure so today i
installed few times a fresh version of 16.04, but with no effect.
I was unable (i had some trouble in compiling the .tar ) to try if the
2016c version was working.
I cant downgrade to 14.04 because i need an higher version of gretl and but i cant work with this trouble.
So - really - any help or suggestion is very appreciated.
