From 1 March 2023, Probability in the Engineering and Informational Sciences will be moving to a Gold Open Access publishing model. All accepted articles from this date will be published with a non-exclusive Gold Open Access CC-BY licence, and will be subject to an Article Processing Charge (APC). Many corresponding authors will have their APC covered by a transformative agreement; check here to see if your institution is covered. Any author without funding or not covered by a transformative agreement can apply for a waiver.
