gretl 1.6.0-pre for OS X (Allin Cottrell)
by Florent Bresson
When will you release the 1.6 version please ? I'm
very busy now and I won't be able to work on the
french traduction till mid august.
I also would like to traduce in french the gretl
homepage, but I don't know anything about html. Would
it be possible for me to send just a raw text file ?

Just a minor cosmetic issue
by James Wells
When I run a WLS regression with het-robust std. errors, and copy RTF, I get
Model 1: WLS estimates using the 49 observations 1-49
Dependent variable: depvar
Heteroskedasticity-robust standard errors, variant HC1Variable used as
weight: weightvar
It seems that there should be a newline between HC1 and Variable.

Suppressing comand output in Gretl
by Johannes Fichtinger
Dear all,
just a simple question about text output of gretl:
The following script:
outfile temp.txt --write
printf "Model 1: R2 = %.8g, e2sum = %.8g\n", R2_m1, e2sum_1
returns in temp.txt:
? printf "Model 1: R2 = %.8g, e2sum = %.8g\n", R2_m1, e2sum_1
Model 1: R2 = 0.12531817, e2sum = 4512.596
How can I turn off the printing of the command line: ? printf ... and just see
the "real" output?
@ Sven Schreiber:
Thanks for your script, is working well!
Greetings,

Hello Group, On Shaza and other toos
by Allan_Bart＠ibi.com
Hello,
I own several packages; Xplore, R, Gretl Omatrix etc, I am at the the
very basic level. It seems that the open source tools are quckly gaining
in capability. I stillsee estima and several others doing their thing.
What is the expected level of capabillity of Gretl in the area of times
series analysis lets say in a year??

Splash Screen Mark-II
by Talha Yalta
This is the second design that I came up with. I hope you like this
one. I can make small modifications very easily. What do you think?

Exponential moving average
by Johannes Fichtinger
Hi all,
first of all thank you for this powerful und useful piece of software, its
great!
Now I have a little question: I have a time series variable p and want to
creat a new variable called r with the exponential moving average of p, so
r = \alpha*r_{t-1}+(1-\alpha)*p_{t-1}.
Any idea how to create this r? Thanks a lot.

The Splash Screen is here
by Talha Yalta
After some thinking and work, here is the splash screen that I came up
with. I didn't use the existing Gretel image but I think this also
looks good. Please tell me what you think about it. I am also sending
the full quality image as a png file to Allin's personal email. Please
let me know if it is filtered etc. If you insist on the previous
Gretel image, I can probably come up with something else featuring it.
However, I think most people cannot immediately associate that image
with Gretel.
Finally, I can make all sorts of tweaks and adjustments. Just tell me.
Jack says that:

I totally agree. That is why I left the upper right part empty. This
will be filled by the program displaying the relevant information.
Again, I can change things to suit needs.
Have a great day...

GUI modification...
by Mihai Nica
Greetings:
I would have a small question/request. Would it be much too difficult to somehow emulate the way eviews GUI allows one to transform data (make calculations) within the models themselves? [i.e. y c log(z/p) g/a b (c+b)
]. Frankly, the only reason I use R primarily (which is way beyond my needs aside the graphic capabilities) is that in gretl I have to transform data first and then run the analysis, and so on
Am I making any sense :-)?
Thanks,
mihai

Forwarded message from Allan Bart
by Allin Cottrell
For some reason the following got posted to gretl-users-bounces;
I'm sending it on to the list. Anyone familiar with Shazam?

Hello,
I own this book and I was wondering if Gretl is up to
the state of Shazam of a couple years ago.

QR versus Cholesky decomposition
by Talha Yalta
Professor Cottrell:
During my testing of gretl using the StRD linear regressions test
suit, I found that QR decomposition performs better than the Cholesky
decomposition and sent you a pdf file containing a table comparing the
two methods. QR method mostly creates higher number of accurate digits
and is able to produce a solution for the Flip data set, where
Cholesky fails.
In the light of this evidence I wrote my paper and prepared the
summary tables assuming the new default for linear regressions would
be the QR decomposition. I see that the new snapshots still have
Cholesky as the default. If Cholesky will stay as the default in the
new version, please let me know so that I can update my tables.
I am attaching the pdf file containing the comparisons.
Sincerely,
Talha
