This book develops the major themes of time series analysis from its beginnings in the early part of the 20th Century through to the present day. This is done by uniquely concentrating on the research of six distinguished British statisticians, Udny Yule, Maurice Kendall, James Durbin, George Box and Gwilym Jenkins, and Clive Granger, all of whose work is characterized by the British traits of pragmatism and the desire to solve practical problems of importance, accompanied by great technical skill and unusual integrity. Many of the key examples and graphics found in the seminal articles of these authors are recreated and their original voices are provided so that their readers can become acquainted with the contemporary views of the protagonists. This book should be of interest to anyone who desires an historical appreciation of the development of time series analysis and it also provides an essential background to current advanced textbooks on the subjects
