Dear all,
this message is to inform the community about the activity in our function package repository: during the month of May 2026, 1 new package was added to our repository and 2 packages were updated to a new version.

The new package is

"MAR", by A. Bucci, G. Palomba and M.Tedeschi (Matrix autoregressive models)

The updated packages are

"CUB", by F. Di Iorio, R. Simone and me (CUB mixture model for ordinal data)
"series_calculator", by Sven Schreiber (calculate and add new series to dataset via the GUI)

The new "MAR" package is best described in the paper presented at the last Gretl conference in Birmingham that you can find here. In a nutshell, a MAR model is for matrices what a VAR model is for vectors. Cool stuff.

As for the "CUB" package, you can now perform weighted estimation and use some new graphic functions. The update to "series_calculator" is basically a bugfix.

As usual, update and enjoy!
