Practice problems and final exam problems

Cryer and Chan present the theory of ARIMA modeling and derive the relevant equations. They explain how to model actual time series, and they provide illustrations. End of chapter exercises give numerical examples of the algebraic equations, but solutions are not in the textbook.

Candidates need worked exercises to understand the material. The discussion forum has practice problems showing how the theory is applied. The final exam problems are like the practice problems, though they are multiple choice questions. If you can solve the practice problems on the discussion forum, you can answer the final exam questions.
