Time-series analysis is a relatively new branch of statistics. Most of thetechniques described in this book did not exist prior to World War II, andmany of the techniques date from just the last few decades. The novelty ofthese techniques is somewhat surprising, given the importance of forecastingin general and of predicting the future consequences of today’s policy actionsin particular. The explanation lies in the relative difficulty of the statisticaltheory for time series. When I was in graduate school, one of myeconometrics professors admitted that he had switched his focus from timeseries when he realized he could produce three research papers a year oncross-section topics but only one paper per year on time-series topics.
