Time Series Analysis pp Cite as. Chapter 3 discussed fitting cosine trends at various known frequencies to series with strong cyclical trends. In addition, the random cosine wave example in Chapter 2 on page 18, showed that it is possible for a stationary process to look very much like a deterministic cosine wave. We hinted in Chapter 3 that by using enough different frequencies with enough different amplitudes and phases we might be able to model nearly any stationary series. Previous to this chapter, we concentrated on analyzing the correlation properties of time series.

Parameter Estimation and Hypothesis Testing in Spectral Analysis of Stationary Time Series

The important data of economics are in the form of time series; therefore, the statistical methods used will have to be those designed for time series data. New methods for analyzing series containing no trends have been developed by communication engineering, and much recent research has been devoted to adapting and extending these methods so that they will be suitable for use with economic series. This book presents the important results of this research and further advances the application of the recently developed Theory of Spectra to economics. In particular, Professor Hatanaka demonstrates the new technique in treating two problems-business cycle indicators, and the acceleration principle existing in department store data. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions.

Singular spectrum analysis SSA is a technique of time series analysis and forecasting combining elements of classical time series analysis, multivariate statistics, multivariate geometry, dynamical systems and signal processing. SSA seeks to decompose the original series into a sum of a small number of interpretable components such as trend, oscillatory components and noise. It is based on the singular value decomposition of a specific matrix constructed upon the time series. Neither a parametric model nor stationarity are assumed for the time series.

If one's objective when performing an analysis is to find a univariate model that produces optimum linear forecasts, it is clear that this objective has been reached if.

Any obvious trend should also be removed prior to spectral estimation. Trend produces aspectral peak at zero frequency, and this peak can dominate the spectrum such that otherimportant features are obscured. After detrending, the next steps are computation of the Fouriertransform, computation of the raw periodogram, and smoothing of the periodogram. Discrete Fourier transform. Say x , x , , x0 1 n is an arbitrary time series of length n.
