Why Statisticians in Government, Banks and Industry Throughout the World Rely on X-11ARIMA/88

When unemployment, production, retail sales and other economic data are released periodically by government agencies, the indicators point to short-term trends and related economic and financial activity. Prior to releasing these important figures to the public, statistical agencies perform extensive analyses to adjust for seasonal fluctuations, which evolve continually from year to year. The method adopted by numerous agencies in government and industry worldwide is the X-11ARIMA/88 seasonal adjustment procedure from Statistics Canada.

The seasonal variations in agriculture, the high pre-Easter and pre-Christmas retail sales, the low level of winter construction are all general examples of the influence of seasonal fluctuations in society.

Analysts in many fields can use X-11ARIMA/88 for applications, which are continually evolving in areas as diverse as manufacturing, banking, insurance, energy production, utility regulation and government.
