Encyclopedia of Statistical Sciences , Update (Volume 1)

Countless professionals and students who use statistics in their work rely on the ten-volume (including supplement) Encyclopedia of Statistical Sciences as a superior and unique source of information on statistical theory, methods, and applications. This new volume is the first of three planned updates designed to bring the Encyclopedia in line with the latest topics and advances made in statistical science over the past decade—in areas such as computer-intensive statistical methodology, genetics, medicine, the environment, and other applications.

Written by over 100 world-renowned experts (including the editors), the entries are self-contained and easily understood by readers with a limited statistical background. Up-to-date bibliographies, thorough cross-referencing, and extensive indexing facilitate quick access to specific information and provide an indispensable platform for further study and research.

With the publication of this first update installment, the Encyclopedia of Statistical Sciences retains its position as a cutting-edge reference of choice for those working in statistics, biostatistics, quality control, economics, sociology, engineering, probability theory, computer science, biomedicine, psychology, and many other areas.
