Package updates (July 2025)
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 July 2025, 1 package was updated to a new version, that is
"PairPlot", by Artur Tarassow (Scatterplot matrix with factor separation)
Plus, a new page is online at https://gretl.sourceforge.net/function_packages.html; it gives an overview of existing packages with a broad coverage of the functionalities they provide.
Sorry if this message comes relatively late in the month, but I am 90% in holiday mode 😉
Download and enjoy!

Granger causality
by Brian Revell
It may be failing memory, but did not earlier Gretl versions include a
Granger causality test? If so, then it has eluded me in the latest one.

Re: R: Query about FEVDs for BVAR
by GIULIA CHIARA
Thank you for your quick response.
If you could, at some point, when it's convenient for you, provide me with an example, it would be extremely helpful since I'm not very familiar with coding.
Thank you in advance for your help. I wish you a good day.
Sincerely,
Giulia Chiara
