The central purpose of Statistical Science is to convey the richness, breadth and unity of the field by presenting the full range of contemporary statistical thought at a moderate technical level, accessible to the wide community of practitioners, researchers and students of statistics and probability. It complements the main scientific journals of the IMS (the four series of the Annals) by coordinating, integrating and explicating important current statistical research. In line with this goal, the journal will publish reviews of influential new methodological and theoretical topics, articles describing substantive areas of scientific research with promising statistical applications, interviews with distinguished statisticians and probabilists, and articles on the history of statistics and probability. It may also, exceptionally, publish other material such as evaluations of research papers and books, discussions of classic articles with commentary on their contemporary impact, and articles on educational programmes.
