An Extended Review of the X11ARIMA Seasonal Adjustment Package

Stuart Scott


The revised version of X11ARIMA, Statistics Canada's seasonal adjustment package, is reviewed. The 1988 package, available for PC's as well as mainframes, is easy to use and more flexible than the 1980 version. New features reflecting research by Estela Dagum and her colleagues are highlighted. Comparisons are made with some other available X-11 programs.
