Researchers from the Center for Statistics and Applications in Forensic Evidence (CSAFE) will present posters and papers at the 2023 Joint Statistical Meetings (JSM). JSM will be held Aug. 5-10 in Toronto.
JSM is one of the largest statistical events in the world, offering an opportunity for statistics in academia, industry and government to exchange ideas and explore opportunities for collaboration. This year’s theme is “One Community: Information Decisions and Driving Discovery” and will feature invited and contributed technical sessions, poster presentations and other activities. For more information, visit https://ww2.amstat.org/meetings/jsm/2023.
CSAFE researchers will share the latest advancements in their research activities using statistical methods. Below is the list of presentations and poster submissions. An asterisk (*) denotes a CSAFE researcher.
