Version 1.1
Introduction
The X-13ARIMA-SEATS seasonal adjustment program is an enhanced version of the X-11 Variant of the Census Method II seasonal adjustment program (Shiskin, Young, and Musgrave 1967). The enhancements include a more self-explanatory and versatile user interface and a variety of new diagnostics to help the user detect and remedy any inadequacies in the seasonal and calendar effect adjustments obtained under the program options selected. The program also includes a variety of new tools to overcome adjustment problems and thereby enlarge the range of economic time series that can be adequately seasonally adjusted. Examples of the use of these tools can be found in Findley and Hood (1999). Basic information on seasonal adjustment is given in Chapter 2 of Dagum and Cholette (2006) and in Chapter 1 of Ladiray and Quenneville (2001), where the X-11 method is thoroughly documented.
