Panel data
by SILVIANA SANTOSO
Hello,
I want to ask several question about panel data in gretl.
I currently working on my thesis that use panel data. I have already tested
my data to choose the right models (pooled/fixed/random). My model is fixed
effect models. Then I want to test its normality and heteroscedasticity.
I have tried to click on test > heteroscedasticity > groupwise. My model is
suffered the heteroskedasticity problem. So I tried to rectify my model
from heteroskedasticity by ticking the robust standard error arellano. But
by model still suffer of heteroskedasticity problem. So what should I do?
And about normality my model is not distributed normaly but I don't know
how to rectify it in gretl
Hope you may give a solution to my problem. Thank you in advance
Sincerely,
Silviana Gunarsih Santoso

Importing weekly data: bug?
by Matteo Pelagatti
Hi Gtretlers
I am trying to assign a date to weekly data. The guided import procedure
asks me how I want to name the week (Daily date to represent week), I
select "Monday" and than the following window appears:
I guess that 664903 is the internal representation of the date, but I
would have expected something like "2006-01-02".
Is this a bug, or I am missing something?
Best,
Matteo

windows gnuplot
by Riccardo (Jack) Lucchetti
Folks,
a PhD student here just reported the most bizarre problem: if you try this
<hansl>
nulldata 20
setobs 5 1960-01-01
x = normal()
gnuplot 2 --time-series --output=display
</hansl>
on linux, everything is fine. On windows 8.1, gnuplot barfs out an error.
However, if you change the starting date to 1970-01-01, everything is ok.
(This is gretl 2018a with gnuplot 5.2 patchlevel 4)
I have an idea on what may be wrong here, but I'd like people who use
windows to confirm if they see the bug too.

Bug?
by Andreas Zervas
Dear all,
I am sending this email because lately I have observed changes in the way gretl interacts with octave. I am attaching a simple program for illustrative purposes. I think that such a program should work in any case.
I think it works in linux with no problems (based on earlier experience with more detailed programs to produce graphs).
The issue is that I was able to run this program under windows 7 with earlier gretl and octave versions, in particular it works under gretl version up to 2016d and old octave versions - works with octave 3.4.3. However, under win 7 it does not work with late octave versions - does not work with octave 4.2.1.
In any case, I cannot make it work under win 10, no matter which version of gretl (I have used 1.9.92, 2016d, 2017d) and octave (3.4.3, 4.2.1) I use.
Could you take a look on this issue?
Kind regards,
Andreas Zervas
P.S. I originally started coding with octave because gretl does not offer a facility to produce subplots (graphpage is an imperfect substitute, and accepts only up to 8 graphs I think, while scatters accepts only one variable on each graph). I also did not like the idea of learning another language just to plot, when I am familiar with matlab / octave. Any plans for such a feature?
