Summary
Virtually any random process developing chronologically can be viewed as a time series. In economics closing prices of stocks, the cost of money, the jobless rate, and retail sales are just a few examples of many. Developed from course notes and extensively classroom-tested, Applied Time Series Analysis with R, Second Edition includes examples across a variety of fields, develops theory, and provides an R-based software package in CRAN (tswge) to aid in addressing time series problems in a broad spectrum of fields. The material is organized in an optimal format for graduate students in statistics as well as in the natural and social sciences to learn to use and understand the tools of applied time series analysis.
Features
- Gives readers the ability to actually solve significant real-world problems
- Addresses many types of nonstationary time series and cutting-edge methodologies
- Promotes understanding of the data and associated models rather than viewing the series as the output of a "black box"
- Over 150 exercises and extensive support for instructors
New to the Second Edition
The second edition has several enhancements that make it an ideal text for a stand-alone one semester or a two semester course in applied time series analysis. New features include:
- An accompanying, easy to use R package that includes 50+ functions for analyzing time series data and producing associated graphical presentations
- Many additional real-world data sets, all of which are included in the accompanying R package. The package contains about 100 data sets (real and simulated).
- Discusses new advances in the analysis of long memory and data with time-varying frequencies (TVF).
