This volume of mathematical tables has been prepared under the aegis of the Institute of Mathematical Statistics, which is a professional society for mathematically-oriented statisticians. The purpose of the Institute is to encourage the development, dissemination, and application of mathematical statistics. The Committee on Mathematical Tables of the Institute of Mathematical Statistics is responsible for preparing and editing this series of tables. The tables included in the present volume were checked at the University of Victoria. Dr. R. F. Odeh arranged for, and directed this checking with the assistance of Mr. Bruce Wilson.
