What is Seasonal Adjustment? (pdf) Seasonal adjustment is a
statistical technique which eliminates the influences of weather,
holidays, the opening and closing of schools, and other recurring seasonal
events from economic time series. This permits easier observation and
analysis of cyclical, trend, and other nonseasonal movements in the data.
By eliminating seasonal fluctuations, the series becomes smoother and it
is easier to compare data from month to month. |
