Stationary Stochastic Processes: Theory and Applications
Features
- Introduces the theory and applications of advanced stochastic processes
- Includes all basic theory together with recent developments from research in the area
- Utilizes a rigorous and application-oriented approach to stationary processes
- Explains how the basic theory is used in special applications like detection theory and signal processing, spatial statistics, and reliability
- Opens the doors to a selection of special topics for the teacher to expand on, like extreme value theory, filter theory, long-range dependence, and point processes
Summary
Intended for a second course in stationary processes, Stationary Stochastic Processes: Theory and Applications presents the theory behind the field’s widely scattered applications in engineering and science. In addition, it reviews sample function properties and spectral representations for stationary processes and fields, including a portion on stationary point processes.
Features
- Presents and illustrates the fundamental correlation and spectral methods for stochastic processes and random fields
- Explains how the basic theory is used in special applications like detection theory and signal processing, spatial statistics, and reliability
- Motivates mathematical theory from a statistical model-building viewpoint
- Introduces a selection of special topics, including extreme value theory, filter theory, long-range dependence, and point processes
- Provides more than 100 exercises with hints to solutions and selected full solutions
This book covers key topics such as ergodicity, crossing problems, and extremes, and opens the doors to a selection of special topics, like extreme value theory, filter theory, long-range dependence, and point processes, and includes many exercises and examples to illustrate the theory. Precise in mathematical details without being pedantic, Stationary Stochastic Processes: Theory and Applications is for the student with some experience with stochastic processes and a desire for deeper understanding without getting bogged down in abstract mathematics.

Editorial Reviews
This book offers quite a unique approach and selection of topics within the modern field of stochastic processes. It aims at providing theoretical insight to graduate students and researchers in engineering and science … also those coming from the theoretical side who want to know more about the applications will benefit from this book. A common theme for the book is the bridge-building between different audiences. … Without being mathematically over-demanding, the book builds up the relevant theory in a very intuitive yet rigorous way that helps the reader to a deeper understanding of definitions and results that could otherwise be mystifying. This intuition-driven approach also provides a common thread throughout the book.

In the same vein as the classic works by Cramér and Leadbetter and Yaglom, Lindgren’s book offers both an introduction for graduate students and valuable insights for established researchers into the theory of stationary processes and its application in the engineering and physical sciences. His approach is rigorous but with more focus on the big picture than on detailed mathematical proofs. Strong points of the book are its coverage of ergodic theory, spectral representations for continuous- and discrete-time stationary processes, basic linear filtering, the Karhunen–Loève expansion, and zero crossings. While the text is mainly focused on one-dimensional processes, there is also coverage of vector-valued processes and random fields. Particularly appealing features of the book are its numerous examples and remarks (some providing interesting historical background). The structure of the book is such that it can be recommended both as a classroom text and for individual study.

From my start as a graduate student in probability and statistics, Stationary and Related Stochastic Processes by Cramer and Leadbetter has always been one of my favorites. … In many respects, Lindgren’s Stationary Stochastic Processes: Theory and Applications is an updated and expanded version that has captured much of the same spirit (and topics!) as the Cramer and Leadbetter classic. While there have been a number of new and good books published recently on spatial statistics, none cover some of the key important topics such as sample path properties and level crossings in a comprehensive and understandable fashion like Lindgren’s book. This book is required reading for all of my PhD students working in spatial statistics and related areas.

Georg Lindgren's new book is a most attractive presentation of the theory and application of these processes, with an emphasis on second order properties and Fourier methods. The theory is described with a view towards application but the treatment does not duck the technical mathematics; rather it presents, honestly and clearly, all mathematical ideas that are needed, accompanying them by motivation and interpretation that keep the wider purpose in mind. … The choice of topics is consistent with the general approach: interesting, engaging, giving the reader ample evidence of the utility of the theory and showing how practical needs drive it forward. … the book is authoritative and stimulating, a worthy champion of the tradition of Cramer and Leadbetter admired by the author (and many others). It is a rich, inspiring book, full of good sense and clarity, an outstanding text in this important field.

It is with a great pleasure I welcome this book by Prof. G. Lindgren. At first thought, it seems that such a book is redundant as this is a classical theme well covered by classical texts. But it is not! This book is a unique blend of classical theory and application theory —where stochastic processes theory meets applications in engineering and science. I particular enjoyed the chapter about level crossings and excursions … . The book is very well written, the themes are well chosen and the style is relaxed but precise without being pedantic. My only regret is that this book did not appear earlier! This book is highly recommended!
