From the Editors: Probability Approximations, Anti-Terrorism Strategy, and Bull's-Eye Display for Performance Feedback

This “From the Editors” column is coauthored by new Editor-in-Chief Rakesh K. Sarin and former Editor-in-Chief L. Robin Keller. Our first two articles are on techniques for approximating probability distributions. The first article, by Robert K. Hammond and J. Eric Bickel is on “Reexamining Discrete Approximations to Continuous Distributions.” Next, Luis V. Montiel and J. Eric Bickel present a method for “Approximating Joint Probability Distributions Given Partial Information.” The next two articles present methods for analyzing terrorist threats or measures for terrorist protection. Kevin Ni, Daniel Faissol, Thomas Edmunds, and Richard Wheeler present a new method for “Exploitation of Ambiguous Cues to Infer Terrorist Activity.” The next article is on “Passenger Profiling and Screening for Aviation Security in the Presence of Strategic Attackers” by Huseyin Cavusoglu, Young Kwark, Bin Mai, and Srinivasan Raghunathan. Our final paper is on “WholeSoldier Performance Appraisal to Support Mentoring and Personnel Decisions,” by Robert A. Dees, Scott T. Nestler, and Robert Kewley.
