just a quick notice that recently two new contributed function packages
have seen the light of the gretl world:
- 'ARprobit', which implements the Kauppi&Saikkonen approach to estimate
a dynamic Probit model including an autoregressive term (in addition to
lags of the dependent dummy).
- 'hamilcycle', which applies the simple but already popular proposal by
Hamilton to do a regression-based filter of a time series to obtain a
cyclical component (based on an idea by Jack a year ago)
As always (sorry for being repetitive) you can get these and other
contributed packages online from within gretl ("fx" button at the
bottom, or through the menu File/Function packages/On server).
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).
I refer to to an old problem. Requesting a bundle of data from
dbnomics database after the versions "dbnomics 2.0" is very slow. It
seem to be correlated to the reason that all metadata of the times
series are transmitted and not only the values. With a newer version of
the api v22 it is possible to eleminate the metatdata. See the mail
below I have got from the folks of dbnomics.
Is there the the possibility to change the "dbnomics 0.39" in that way
which comes with the version 2021b of gretl for MS-Windows?
Hi @Klaus <https://forum.db.nomics.world/u/klaus>, we added a |metadata|
argument that can be set to false to disable metadata.
It is documented in API doc: http://api.db.nomics.world/v22/apidocs
I just noticed that in a gdt dataset the names of the variables imported
from a spreadsheet cannot be changed (error of command rename: "the
variable x is read-only"). Far enough, not much of an issue, but I am
curious: what is the rationale?

Unfortunately the graph of a sequence of tau values using Robust

helpful if it were, even just to be able to change the title so one can
remember what the dependent variable was when next viewed.

as you know, gretl is one of very few scientific programs that support
regional-specific settings for the decimal number separator. (It can
handle the decimal comma, except if you're scripting yourself with the
built-in hansl language, where the decimal point/period is mandatory
Recently we found out that this support caused a bug with some
contributed packages, especially when they produce plots. The bug would
only bite if you ran gretl with a decimal comma setting. (Note that even
if you run gretl with a translated interface, you are not necessarily
using the decimal comma, because that also depends on the user setting
"use locale-specific decimal separator". For example, I typically run
gretl in German, but not with the decimal comma.)
We identified the following six affected packages and then asked the
respective authors to fix them with respect to this subtle bug:
* heatmap.gfn -- heatmap plots
* kddensity.gfn -- kernel estimation of bivariate densities
* gnuplot_piechart.gfn -- A simple 2D pie chart
* yahoo_get.gfn -- Downloader of daily financial data from Yahoo
* CUB.zip -- Uniform-Binomial mixture model for ordinal data
* MDS.gfn -- Multidimensional Scaling
These packages have now been updated and fixed. So if in the past they
failed when you tried them, perhaps you should try again with the new
Also, let me stress again that bug reports are very important. Of course
the individual package authors are responsible for their packages, but a
subtle bug like this one really cannot be blamed on anybody. So don't
hesitate to report failures of contributed function packages here on the
