Editorial announcement

On behalf of both the editorial board and the readership of the Journal of Time Series Analysis, I would like to take this opportunity to thank Professor Steve Leybourne and Professor Dag Tjøstheim very much for their dedicated service as Co-Editors of the Journal of Time Series Analysis since January 2013, and as Associate Editors of the journal prior to that. Both have stepped down with effect from 28th February 2023. I am, however, very pleased to announce that both Steve and Dag have agreed to become Advisory Editors of the Journal of Time Series Analysis in each case with effect from 1st March 2023.

I am delighted to welcome Alexander Aue and Christian Francq as new Co-Editors of the Journal of Time Series Analysis, in each case effective from 1st March 2023.
