X-12-ARIMA is the widely used seasonal adjustment software produced, distributed, and maintained by the Census Bureau. It is used for all official seasonal adjustments produced by the U. S. Census Bureau.
Features include:
There are distributions of X-12-ARIMA for Windows® PC and Linux/Unix platforms. For Windows systems, the Census Bureau's Win X-12 interface program is recommended, but it is also possible to execute the program using command line input.
In addition, a SAS®/Graph program named X-12-Graph is available that allows users to generate useful graphical diagnostics from X-12-ARIMA output. It requires no knowledge of SAS®, and can generate more types of graphs than Win X-12.
