I read a copy of Rob J. Hyndman and George Athanasopoulos’ “Forecasting: Principles and Practice” which is an extensive and understandable introduction to the fundamentals of forecasting. The book, which is free to download online, covers a variety of forecasting approaches and techniques with an emphasis on real-world applications. It offers detailed instructions for putting forecasting models into practice and is especially meant for readers who have a working knowledge of basic statistics.
The writers present basic ideas like decomposition, time series analysis, and different forecasting techniques like ARIMA models and exponential smoothing. The significance of comprehending the data and selecting suitable models according to the time series properties is emphasized throughout the book. The text is filled with real-world examples and case studies that enable readers to put the writers’ perspective in mind.
