For a guide to JSM presentation types, see their sessions guidelines. ...And, if you're a Vanderbilt trainee, staff, or faculty member, consider preparing a submission for JSM 2024, in Portland, Oregon. Proposals for invited talks are due September 7, short courses by September 30, topic-contributed proposals by December 7, computer tech workshops by January 15, and contributed papers by February 1. The theme for 2024 is "Statistics and Data Science: Informing Policy and Countering Misinformation." Also, JSM 2025 will be in Nashville, from August 2 through 7, as will the Institute of Mathematical Statistics' New Researchers Conference.
