An earlier version of this article was presented at the 2009 annual meeting of the American Political Science Association, Toronto, Canada. We appreciate the comments and suggestions we received from John Ahlquist, Hyeran Jo, Francisco Pedraza, and from colleagues associated with the ICEWS project, especially Sean O’Brien, Philippe Loustanau, and Laura Stuart. Colleagues at the 10th Anniversary Conference on Statistics and the Social Sciences, at the University of Washington, Seattle, WA, also provided useful input, especially Andrew Gelman and Steve Fienberg. We also presented a version of these ideas at the 2009 Summer Political Methodology Conference at Yale University and received valuable reactions from a variety of colleagues. Despite all this good advice, we remain responsible for results presented herein. This project was partially supported by the Information Processing Technology Office of the Defense Advanced Research Projects Agency aimed at producing models to provide an Integrated Crisis Early Warning Systems (ICEWS) for decision makers in the U.S. defense community. The holding grant is to the Lockheed Martin Corporation, Contract FA8650-07-C-7749. The anonymous reviewers and editor made exceptionally helpful comments.
