Gretl-Hansl "IDE" for Sublime editor
by Artur Tarassow
Dear all,
some weeks ago I've started to switch to the sublime editor
(https://www.sublimetext.com/) for writing gretl code.
Even though I like the simplicity of the gretl editor and its features
such as syntax highlighting and auto-itendation, it lacks some features
of modern IDEs such as "goto-anything", "goto-definition", custom
keybindings, fancy themes, git-implementation, snippets etc. which make
life much easier when working on larger projects. Don't get me wrong,
the gretl editor is great but was _never_ supposed to become a proper
software-development IDE but rather has another focus which is totally fine.
So I started to write the "Hansl-Gretl-Language" package for sublime
which includes the following features:
- 3 gretl build-systems (client mode, batch mode, and REPL mode) for
executing hansl code by means of sublime (plots are also working!)
- syntax-highlighting
- completion of gretl commands, accessors and keywords
- some snippet examples for speeding up coding
The project still has the following (known) issues:
- no auto-itendation (still have to figure out how this works)
- issues with some corner-cases which are not syntax-highlighted (regex
can become so hard!)
The package can be downloaded through sublimes package control system,
and can be found here:
https://packagecontrol.io/packages/Hansl-Gretl-Language
If somebody wants to participate on this project, check out the code on
my github repository:
https://github.com/atecon/Hansl-Gretl-Language
For those interesting in the sublime editor, check out "OdatNurd"'s
brilliant tutorials on youtube:

Enjoy the package,
Artur

gretl crashes on expanding/closing windows... but probably a MacOs problem
by Artur Bala
Dear gretl developers,
On my MacOS High Sierra 10.13.6, if I "maximize" an output window - be it a
graphic, a script output or a model window - and "close" it
eventually clicking on "x", gretl (2020e-git) crashes; all windows get
closed including gretl's main window. A long and detailed system error
report is also produced (if it can help I can share it with you).
Best,
Artur

Gretl & online teaching
by Stefano Fachin
Like Sven mentioned, conference programs like Meet, Teams and Skype have
the option of sharing the "desktop", which sends to the audience the
entire screen of the lecturer as seen by him/her (at least in Window, do
not know about Mac OS)
bye
Stefano

Hamilton trend-cycle decomposition
by Riccardo (Jack) Lucchetti
Hi all,
yesterday, after having taught my students the HP decomposition, I
wondered if I should also tell them that one of the greatest time-series
econometricians on Earth recently wrote a rather scathing paper entitled
"Why You Should Never Use the Hodrick-Prescott Filter", where he proposes
a simple alternative.
So this morning I rustled up a little script with Hamilton's filter. Here
it is:
<hansl>
function series hamcycle(series y, bool do_plot[1], string title[null])
h0 = 2 * $pd
h1 = h0 + 4
list PROJ = y(-h0 to -h1)
ols y 0 PROJ -q
# ht = $yhat
hc = $uhat
if do_plot
if !exists(title)
title = argname(y)
endif
print title
diff8 = y - y(-h0)
setinfo diff8 --graph-name="Random walk"
setinfo hc --graph-name="Regression"
list PLT = diff8 hc
plot PLT
options time-series with-lines
literal set linetype 1 lc rgb "#ff0000"
literal set linetype 2 lc rgb "#000000"
literal set key top right
printf "set title '%s'", title
end plot --output=display
endif
return hc
end function
# example
nulldata 300
setobs 4 1947:1
open fedstl.bin
data gdpc1 expgsc1 pcecc96
list Y = gdpc1 expgsc1 pcecc96
LY = logs(Y)
strings Titles = strsplit("GDP Exports Consumption")
k = 1
# reproduce part of figure 6
loop foreach i LY --quiet
hc = hamcycle($i*100,,Titles[k++])
endloop
</hansl>
Should we turn this into a function package?

split dependent variable: looking for a test
by Allin Cottrell
This question is not gretl-specific, but answers might show up gretl
features and hopefully it may be of interest.
My dependent variable is the quantity demanded of a certain good, an
hourly time series extending over two years. It exhibits strong
seasonality, both by hour of the day and season of the year; it has
an upward trend; and it's clearly affected by various measures of
weather (temperature, humidity, wind speed). Plain OLS produces
quite a decent fit, but by inspecting the loglikelihood-for-level
figure produced by gretl (via the Jacobian) I can see that taking
the log of the dependent variable gives a better fit. All fine.
However, total demand is the sum of demand from two classes of
consumer -- call them A and B -- and I'm wondering if a better fit
can be obtained by summing the fitted values from separate
regressions, with dependent variables the demand from consumers A
and B respectively. (Note: a Chow test in dummy variable mode is not
applicable, the unit of observation is the hour, not the
transaction.)
My thought was: compute two SSRs in levels, using (restricted) the
exponentiated fitted values from the overall model and
(unrestricted) the sum of the exponentiated fitted values from the
two consumer-class models, then calculate an F test based on the
difference of SSRs in the usual way.
Questions: Does this sound valid? Is there a better way of doing it?
[I'm aware of debate over how best to produce predictions of levels
from log-linear regression, but I'm not sure quite how it applies in
this case.]

Re: Unexpected symbol '§'
by Marcelo Duarte
Hello everyone,
Thanks for the fast answers.
I have realised what hapened.
One variable name had a character not recognised by Gretl (either a tilde
or a cedilla).
The database came from SPSS, which allows this special characters.
Thanks once again.
Marcelo

boxplots C/C++ API
by riles＠triton.net
Hello
I am a bit lost when using the function-> boxplots (const int *list, const char *literal, const DATASET *dset, gretlopt opt)
When dset contains data I get the error-> *** error: allocate_Z called with non-NULL Z, and if dset have no data then I don't know how it would make a boxplot for the data.
Any thoughts on how I would use the C/C++ API to make boxplots?
Thank you
