Uniquely combining theory, application, and computing, this book
explores the spectral approach to time series analysis
The use of periodically correlated (or cyclostationary)
processes has become increasingly popular in a range of research
areas such as meteorology, climate, communications, economics, and
machine diagnostics. Periodically Correlated Random Sequences
presents the main ideas of these processes through the use of basic
definitions along with motivating, insightful, and illustrative
examples. Extensive coverage of key concepts is provided, including
second-order theory, Hilbert spaces, Fourier theory, and the
spectral theory of harmonizable sequences. The authors also provide
a paradigm for nonparametric time series analysis including tests
for the presence of PC structures.
Features of the book include:
An emphasis on the link between the spectral theory of unitary
operators and the correlation structure of PC sequences
A discussion of the issues relating to nonparametric time series
analysis for PC sequences, including estimation of the mean,
correlation, and spectrum
A balanced blend of historical background with modern
application-specific references to periodically correlated
processes
An accompanying Web site that features additional exercises as
well as data sets and programs written in MATLAB(R) for performing
time series analysis on data that may have a PC structure
Periodically Correlated Random Sequences is an ideal text on
time series analysis for graduate-level statistics and engineering
students who have previous experience in second-order stochastic
processes (Hilbert space), vector spaces, random processes, and
probability. This bookalso serves as a valuable reference for
research statisticians and practitioners in areas of probability
and statistics such as time series analysis, stochastic processes,
and prediction theory.
