Stochastic Processes and Long Range Dependence

This monograph is a gateway for researchers and graduate students to explore the profound, yet subtle, world of long-range dependence (also known as long memory). The text is organized around the probabilistic properties of stationary processes that are i

Preface

I first heard about long-range dependence while working on a book on stable processes with Murad Taqqu. Initially, the notion did not seem to stand out among other notions I was familiar with at the time. It seemed to describe simply situations in which covariance functions (or related functions) decayed at a slow rate. Why were so many other people excited about long-range dependence? At best, it seemed to require us to prove some more theorems. With time, I came to understand that I was wrong, and the people who got excited about long-range dependence were right. The content of this phenomenon is truly special, even if somewhat difficult to define precisely. This book is a product of many years of thinking about long memory (this term is synonymous with long-range dependence). It is my hope that i
