searching for underscores in PDF help documents
by Sven Schreiber
Hi all,
why can I sometimes search successfully for underscore characters in
some of the PDF help documents related to gretl , and sometimes not? Or
actually, my hypothesis is that it has to do with how the LaTeX
formatting is done at the source. And so the real question is, how can
we (as the doc authors) make sure that searching is possible?
Example: In the gretl user guide, I enter the search term "eviews_", and
I find the URL in footnote 1 on p. 18 (A4 version). Also, in the help
for the "gig" addon, searching for "gig_set_dist", I get two hits within
the main body. However, the occurrence in the appendix of the same
document isn't found. This is a bit unfortunate.
thanks

RESET
by mayuda
Dear all,
We are using the RESET function and when we try to perform Ramsey's
RESET test in Gretl using only the squares version, the result we get is
the one for cubes and squares with robust estimation. We wanted to know
if there's any reason for this or if it's an error.
I really appreciate any help you can provide.

the "multiplot" package to be retired soon
by Sven Schreiber
Hello everybody,
this is a pre-announcement that the contributed function package
"multiplot" by Artur Tarassow and myself is going to be retired and
removed from the public package server soon. The reason is that since
gretl version 2023c we have the natively built-in "gridplot" facility,
so the multiplot package has become redundant and shouldn't be used anymore.
And here's the usual remark that if for any reason you still need the
package for your own code, please keep a local copy on your system(s).
thanks

Package updates (October 2024)
by Riccardo (Jack) Lucchetti
Dear all,
this message is to inform the community about the activity in our
function package repository: during the month of October 2024, 4
packages were updated to a new version:
"Friedman", by Sven Schreiber (nonparametric test for location difference)
"levene", by Marcos Larios Santa Rosa (Levene's Test for equality of
variance across groups)
"BVAR", by Luca Pedini and Sven Schreiber (Bayesian VARs)
"wstats", by Riccardo "Jack" Lucchetti (more weighted descriptive
statistics)
The most important package among the above is, undisputedly, BVAR: not
only it's a fairly comprehensive and efficient implementation of
Bayesian techniques for VAR models (see
https://link.springer.com/article/10.1007/s00180-024-01492-3). The new
version also features massive performance improvements and offers a
valid alternative to Matlab-based packages such as the BEAR toolbox.
Macroeconometricians, be sure to check it out!

qform speed
by Marcin Błażejowski
Hi,
as long as I understand docs, qform() is not an option if A is identity.
But what if it is diagonal:
<hansl>
set verbose off
r = 20
c = 20
N = 10^6
x = mnormal(r, c)
A = I(c)
A[diag] = mnormal(c, 1)
set stopwatch
loop N
r1 = x'*A*x
endloop
printf "Total time: %f\n", $stopwatch
loop N
r2 = qform(x', A)
endloop
printf "Total time: %f\n", $stopwatch
</hansl>
On my no-so-new i7 8th gen (Haswell) I'm getting:
###########
gretl version 2024d-git
Current session: 2024-11-06 12:33
Total time: 6.207188
Total time: 6.925140
###########
Is that expected?

db.nomics and OECD data
by klaus.hasenbach＠web.de
Hello
I appreciate very much that db.nomics and gretl was able to handle the
new access to the data published by OECD.
When using the menu in gretl (file>databases>dbnomics) I get all series
I want.
But when using the command in a gretl script e.g. "data
OECD/DSD_PRICES(a)DF_PRICES_ALL/AUT.M.N.CPI.PD._T.N.GOY" gretl does not
like the @.
The other way around It works fine with
provider = "OECD"
database = "DSD_PRICES@DF_PRICES_ALL"
bundle spec = defbundle("mask","AUT.M.N.CPI.PD._T.N.GOY")
bs = dbnomics_get_multiple(provider, database, 1000, 0, spec)
dbnomics_bundles_print(bs)
list X = dbnomics_bundles_to_list( bs, "series_code" )
printf "\nHere are the series in list X:\n"
list X print
but surprisingly the bundl request does not work with all data, for
instance not for
provider = "OECD"
database = "DSD_IMTS@DF_IMTS"
bundle spec = defbundle("mask","DNK.W.X.C.M.XDC.Y.N")
bs = dbnomics_get_multiple(provider, database, 1000, 0, spec)
dbnomics_bundles_print(bs)
list X = dbnomics_bundles_to_list( bs, "series_code" )
printf "\nHere are the series in list X:\n"
list X print
Are there ways to solve it?
Thank you very much

Problems opening the Guide from the Help window
by MARCO TEDESCHI
Dear all,
This message is just to inform the community of a crash when trying to open the Gretl guide directly from the help. I am using Gretl 2023c with macOS arm64 (Apple M1 chip). When I try to open the Gretl Guide from command list functions, everything crashes. Let's take the ‘ols’ command as an example: when I try to open the Guide from the last line of the help, Gretl crashed and the attached report is displayed. This issue occurs with all the commands that refer to the Guide. This is not a serious problem, but I wonder if it is my problem or if it can be verified by other Mac users.
Bests,
Marco

New Version 0.2 of the "season_plot" Package
by Artur T.
Dear Gretl users,
I want to announce the release of version 0.2 of the "season_plot"
package for gretl! This update brings some internal enhancements and
changes.
Key Changes in Version 0.2
- Integration with gretl's Built-in gridplot apparatus: We have
transitioned from using the "multiplot" package to gretl's built-in
gridplot apparatus, enhancing the plotting capabilities. This is just an
internal improvement.
- Function Renaming: The function `plot_season_plot()` has been renamed
to `do_season_plot()`. Please note that this change is **backward
incompatible**.
- Parameter Renaming: The following parameters have been renamed for
consistency:
- `PLOT_WIDTH` to `plot_width`
- `PLOT_HEIGHT` to `plot_height`
- `FONT_SIZE` to `font_size`
These changes are also **backward incompatible**.
- New Features:
- A new option for the `type` parameter allows you to plot all
frequencies at once (`type="all"`), which is useful for comparing the
dynamics of all frequency components simultaneously.
- A new `title` parameter has been added to control the title of the
plot.
- You can now specify the number of columns (`cols`) and rows
(`rows`) in the gridplot, applicable only when `type=all` is selected.
- Minimum gretl Version Requirement: The minimum required version of
gretl has been raised to **2024b** due to the use of the new gridplot
apparatus and the `--title` option.
For more detailed information about the package, its functionalities,
and a sample script, please visit the official documentation here:
https://gretl.sourceforge.net/current_fnfiles/season_plot.gfn
We hope you find these updates beneficial for your statistical analyses.
As always, we welcome your feedback and suggestions!
Best,
Artur

obscure sampling problem fixed
by Allin Cottrell
We've recently fixed (in git and snapshots) a somewhat obscure
problem with the "smpl" command in gretl. I say "obscure" because
it's unlikely to affect most users, but here's the sort of thing
that could go wrong.
(1) You open or create a dataset.
(2) You impose a sample restriction that selects a non-contiguous
subset of observations.
(3) You then call a hansl function, to which one or more series are
passed as arguments, and in which "smpl" is used to modify the
sample range.
Now note that by gretl's design it should not be possible inside a
function to modify the sample to include observations that were
excluded at the level of the caller, as in step (2) above.
The following anomalies could arise in certain cases:
* Inside the function, when "smpl" is used more than once, on the
second or subsequent use the sample range might end up including
"excluded" observations.
* Inside the function, a valid use of "smpl" might fail with the
error message "No observations would be left" (i.e. gretl thinks the
sample range would be empty when that's not the case).
To our knowledge these points are now fixed, but if you have any
scripts that match the pattern above, please check that the results
look right. We want to make sure that we aren't missing any bad
cases.
