Definition: Fixed weight index

Category: Seasonal adjustment

Fixed weight indices have a weight structure selected at a particular point in time. The weights represent the relative importance of different products or activities at the weight reference period. Weights are used to compute indices over an extended period. This index compares the values always to the fixed base period. http://ec.europa.eu/eurostat/ramon/statmanuals/files/UNECE_Seasonal_Adjustment_Demetra.pdf
