Add DAta -Data entry Gretl2024d
by Brian Revell
There is still an issue with the add data entry function If a double return
does not register (as is possible when rapidly inputting lots of data
quickly) any simple and move the cursor to the next cell ( ie 2 entries are
typed inadvertently into the same cell, Gretl crashes. So, if the user
input error occurs during a long series of data all previous inputs are
lost. In addition, if the user has not saved any other operation outputs or
analysis before the data entry error occurs, all that is lost too. I
would humbly suggest that any data error entry in the Add Data function
calls up a data entry error warning rather than crashing Gretl.

Inputting new data
by Brian Revell
I seem to be experiencing crashouts of gGretl when adding a new variable or
revising existing data.
After entering an observation and pressing return, the cursor moves to the
next observation cell. However on typing in the next observation, nothing
appears in the cell and Gretl crashes out. This should not happen and is
extremely frustrating. I have never experienced this on earlier versions
(current version 2024d).
The only work around solution is to physically the select the next cell by
clicking on it, and entering the observation data. Harly a streamlined
input process.
Please check.
Given the problem I have had loading k-means clustering package (still not
solved) , I am wondering if I shoudld simply redownload an earlier version
that 2024d?
Advice welcomed.
Brian

Package updates (December 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 December 2024, 3
packages were updated to a new version:
"graphlasso", by Sven Schreiber (graphical Lasso --- l1 shrinkage for
covariance matrices)
"lomackinlay", by Allin Cottrell and Sven Schreiber (Lo-MacKinlay
variance ratio test for determining if a time series is a random walk
process)
"BACE", by Marcin Błażejowski and Jacek Kwiatkowski (Bayesian Averaging
of Classical Estimates)
I'll reserve a special mention for the "graphlasso", which now uses a
new internal function to speed up computation.
Sorry if this message comes relatively late in the month, but I was away ;)
Download and enjoy!

New Version 0.4 of the kmeans package
by Artur T.
Dear Gretl users,
I'm pleased to announce version 0.4 of the kmeans package. This update
includes several important improvements:
1. A new function `kmeans_screeplot()` has been added, which helps in
determining the optimal number of clusters through visual analysis.
2. The `kmeans_plot()` function has been updated to use Gretl's default
values for pointsize and fontsize parameters, providing better
consistency with the overall Gretl interface.
3. We've fixed a bug related to distance measures - the function now
correctly uses the specified distance measure when called through the
GUI, rather than defaulting to the standard measure.
You can update the package through Gretl's package manager. More details
here:

Best regards,
Artur

Contributed package buys_ballot will be retired
by Sven Schreiber
Hi everybody,
this is to pre-announce that the veteran contributed function package
"buys_ballot" by Ignacio Díaz-Emparanza (and Jack Lucchetti, last
updated in 2018) for seasonal plotting will be retired soon from the
public package server. The reason is that its functionality and a little
more is offered by the newer package "season_plot" by Artur Tarassow.
This course of action has been discussed and coordinated with the
package authors.
One restriction to note is that "season_plot" for technical reasons
requires at least gretl 2024b, which is relatively recent. So we are
going to wait for the next gretl release 2024d (which is expected soon)
before retiring the other package. As always, you can continue to use
the package and also store a local copy of "buys_ballot" for further
use. It's probably also going to be archived (@Artur?).
If you notice any problems in your usage with the newer package
"season_plot", now would be a great time to report it. (on- or off-list)
thanks
sven
