This is an introduction to time series that emphasizes methods and analysis of data sets. The logic and tools of model-building for stationary and non-stationary time series are developed and numerous exercises, many of which make use of the included computer package, provide the reader with ample opportunity to develop skills. Statisticians and students will learn the latest methods in time series and forecasting, along with modern computational models and algorithms.
so much is left out for the reader to figure out - coming back to the same pages - 48 and 78 looking for information about causal and invertible AR/MA processes which isnt there.
Alot of examples, but missing corollaries. Still this is the reference text.
