X-13ARIMA-SEATS is a seasonal adjustment software produced, distributed, and maintained by the Census Bureau.
The Census Bureau is in the final stages of transitioning from using X-12-ARIMA to X-13ARIMA-SEATS, with most groups within the Census Bureau producing seasonal adjustments with X-13ARIMA-SEATS rather than X-12-ARIMA.
There are distributions of X-13ARIMA-SEATS for Windows® PC and Linux/Unix platforms. For Windows systems, the Census Bureau's Win X-13 interface program is recommended, but it is also possible to execute the program using command line input.
Note that the version of SEATS in this release of X-13ARIMA-SEATS is not the version that will soon be released by the Bank of Spain as SEATS+. The Census Bureau is currently integrating that version of SEATS into a future release of X-13ARIMA-SEATS; a beta version of that release should be available soon.
We are indebted to Agustín Maravall, Gianluca Caporello, and their unit at the Bank of Spain for their collaboration and advice in the development of this software.
In addition, a SAS/Graph® program named X-13-Graph is available that allows users to generate useful graphical diagnostics from X-13ARIMA-SEATS (as well as X-12-ARIMA) output. It requires no knowledge of SAS®, and can generate more types of graphs than Win X-13. There is a Java version of the software available as well.
