Defense and Aerospace Test and Analysis (DATA) Workshop is the result of a multi-organization collaboration with the Director of Operational Test & Evaluation within the Office of the Secretary of Defense, NASA, the Institute for Defense Analyses (IDA), and the Section on Statistics in Defense and National Security (SDNS) of the American Statistical Association. The workshop is strategically designed to strengthen the community leveraging rigorous statistical approaches to test design and analysis of data in defense and aerospace.  The workshop will have a mix of applied problems, unique methodological approaches, and tutorials from leading academics.  The goal is to facilitate collaboration among all involved, including expanding our impact to other government agencies.
