Famous Quotes from the Book

"Forecasting is the science—or art—of predicting future values of a series based on previously observed data."

"Time series analysis is not just about fitting a model; it is about understanding the underlying structure and dynamics of the data."

"An effective model is one that not only fits the historical data well but also performs accurately in predicting future outcomes."
