THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Proceedings of a Workshop on Statistics on Networks
Preface and Workshop Rationale
On September 26 and 27, 2005, the Committee on Applied and Theoretical Statistics of the National Research Council conducted a 2-day workshop that explored statistical inference on network data so as to stimulate further progress in this field. To encourage cross-fertilization of ideas, the workshop brought together a wide range of researchers who are dealing with network data in different contexts. The presentations focused on five major areas of research: network models, dynamic networks, data and measurement on networks, robustness and fragility of networks, and visualization and scalability of networks.
Disciplines such as biology, social sciences, and telecommunications have created different kinds of statistical theory for inference on network data. The workshop was organized to draw together experts from the various domains and to facilitate the sharing of their statistical, mathematical, and computational toolkits. The ubiquity of networks and network data created a challenging environment for the discovery of common problems and techniques.
The overall goals of this report, which is produced only on a CD and not in printed form, are to improve communication among various communities working on problems associated with network data and to increase relevant activity within the statistical sciences community. Included in this report are the full and unedited text of the 18 workshop presentations, the agenda of the workshop and a list of attendees (Appendix A) and biographical sketches of the speakers (Appendix B). The presentations represent independent research efforts on the part of academia, the private sector, federally funded laboratories, and government agencies, and as such they provide a sampling rather than a comprehensive examination of the range of research and research challenges posed by massive data streams.
This proceedings represents the viewpoints of its authors only and should not be taken as a consensus report of the Board on Mathematical Sciences and Their Applications or the National Research Council.
