Classic – Airline Passenger Data

In this week’s “Tips and Tricks” newsletter, we present the analysis, modeling, and forecast for international airline passenger data. We make use of a familiar example that first appeared in Time Series: Forecast and Control, a textbook by Box, Jenkins, and Reinsel, originally published in 1969. (ISBN: 0470272848)

The international airline passenger series documents the monthly totals of airline passengers between Jan 1949 and Dec 1960.

Our objective with this exercise is to follow the same analysis found in Time Series and to demonstrate the accuracy of NumXL calculations. Furthermore, a leading statistical software vendor – SAS – presents its own analysis for the same data set, so we strongly recommend that our users review the analysis on the SAS support site as well.
