Abstract

Techniques involving the direct study of the spectrum when analyzing time-series are reviewed, and comments made on such topics as estimating the spectral density function, testing for mixed spectra, eliminating a trend, cross-spectral analysis, and non-normality. Recent extensions of spectral analysis by the author to point and line processes are illustrated by reference to traffic data, including an estimate of the flow-density relation from a cross-spectral analysis.
