Seasonal Adjustment

    (Department of Economics, University of Aarhus, Denmark)

The main objective behind the production of seasonally adjusted time series is to give an easy access to a common time series data set purged of what is considered seasonal noise. Although the application of o¢ cially seasonally adjusted data may have the advantage of being cost saving it may also imply a less e¢ cient use of the information available, and one may apply a distorted set of data. Hence, in many cases, there may be a need for treating seasonality as an integrated part of an econometric analysis. In this article we present several di¤erent ways to integrate the seasonal adjustment into the econometric analysis in addition to applying data adjusted by the two most popular adjustment methods.
