X-12-ARIMA

X-12-Graph Download Page

X-12-Graph is a program developed at the Census Bureau to provide graphical diagnostics for the Bureau's X-12-ARIMA seasonal adjustment program. The original program was developed as a SAS Macro program; there also a Java implementation of the software.

X-12-Graph allows the user to:

• Select from 14 types of graphs;
• Compare different X-12-ARIMA adjustments;
• Choose options for the graphs, such as starting and ending dates, scale, and colors;
• Save the graphs in a variety of formats.

Our goal in creating X-12-Graph was to provide specific types of time series graphs in a package that would be easy for everyone to use. The original version of X-12-Graph is programmed with the SAS^® System but requires no previous SAS experience from the user.

Documentation and examples for the X-12-Graph program are also available, as well as documentation for the X-12-Graph Batch Windows Interface.

Changes from the previous version

Batch Version 1.6 includes the following new graphs:

• forecast graphs for comparing two adjustments;
• spectrum graphs for comparing two adjustments;
• additional graphs for plotting indirect adjustments;
• two new graphs were added to the history graphs for comparing two adjustments, allowing the percent differences of the month-to-month percent changes of the seasonal adjusted values and the trend to be shown.

Some program defects have been found and fixed.
