Seasonal Adjustment Module
The X11 adjustment module for RATS is our implementation of the Census Bureau's X11 seasonal adjustment procedure. The module adds "X11" as an additional instruction built into the RATS software.
This combines the X11 procedure with all of the data-handling power and time-series analysis capabilities of RATS, and makes it easy to do adjust many series. Features of the X11 module include:
• Adjusts both quarterly and monthly data.
• Options for trading day and holiday adjustments.
• Graduated extremes options for handling outliers.
• Can easily adjust large numbers of series.
