The International Workshop in Sequential Methodologies (IWSM) is a biannual conference dating back to 2007 that seeks to bring together statisticians, at all stages of their careers, from academia as well as from industry, to present, discuss, and explore the latest developments, challenges and opportunities in theoretical and applied sequential statistical methods. The Workshop covers all aspects of sequential statistics, from optimal stopping, sequential estimation and hypothesis testing, and quickest change-point detection, to applications in information theory, quality control, clinical trials, finance, and cybersecurity – to name a few.
