Title:	Compact Output for Quickly Analyzing Seasonal Adjustment Diagnostics

Abstract:	One of the major problems with any seasonal adjustment technique is how to easily analyze the results when large numbers of series are adjusted. Recent improvements in seasonal adjustment programs to "automatically" identify models, outliers, etc., do not always work well or address all potential problems. Traditional measures, such as quality-control statistics, also are not usually sufficient by themselves to judge an adequate adjustment. Many useful diagnostic tools are not produced by standard seasonal adjustment programs, thus a customized battery of diagnostic graphs and statistics may be required. This poster session shows how large amounts of useful diagnostic information can be stored in compact pdf files for more efficient analysis of seasonal adjustment quality. Examples of output from seasonal adjustment of household labor force data will be shown.
