Paper detail

Editorial

Clauset and Woodard (2013) ask, "What is the likelihood of another September 11th-sized or larger terrorist event, worldwide, over the next decade?" This question has implications for numerous policy arenas - national security, international relations, public safety, disaster preparedness, and so on - but it also has resonance for any individual who remembers 9/11. Thus, the Area Editors chose this paper to engage the audience at the 2013 Joint Statistical Meetings (JSM) in Montreal. The discussions in this issue of The Annals of Applied Statistics include those presented formally at JSM 2013 as well as others from individuals who were unable to attend JSM 2013 or who contributed discussions after the meeting.
