Hamilton, a professor of economics at the University of California San Diego, Time Series Analysis covers the fundamental concepts and theories of time series analysis. Since the assembly of season length candidates by periodic regression usually produces one or two clear winning lengths if seasonality actually exists in the data, the return of a single candidate indicates likely seasonality. If there are no likely season length candidates, only the non-seasonal models are estimated. The co-author Paul Cowpertwait also features the data sets on a companion website. Website: Site | Amazon.
