The book "Scan Statistics" provides a comprehensive introduction to the analysis of event clusters in temporal or spatial data. It is aimed at scientists and professionals who are concerned with the question of whether observed clusters of events have occurred randomly, assuming that these events are independent and uniformly distributed. The application of scan statistics can be found in numerous disciplines, including geology, medicine, geography, and quality assurance. The work addresses both theoretical and practical aspects and offers valuable insights into the methodology of cluster analysis. The authors, Joseph Naus and Joseph Glaz, contribute their expertise in mathematics and natural sciences to highlight the relevance and applicability of these statistical techniques.
