Annals of the Institute of Statistical Mathematics (AISM) aims to provide a forum for open communication among statisticians, and to contribute to the advancement of statistics as a science to enable humans to handle information in order to cope with uncertainties. It publishes high-quality papers that shed new light on the theoretical, computational and/or methodological aspects of statistical science. Emphasis is placed on (a) development of new methodologies motivated by real data, (b) development of unifying theories, and (c) analysis and improvement of existing methodologies and theories. It also seeks to contribute to statistical science in machine learning and econometrics. AISM is trying to make faster decisions after the reception. For example, around 60%, 80%, and 90% of submissions received from July 2019 to June 2020 had a review time from receipt to first decision of 1, 3, and 5 months or less, respectively.
