imputacja z użyciem średniej cen danej klasy produktów (ang. bridged overlap) Explanation: This is a descriptive definition. ccccccccccccccc Overlap, bridged overlap (class-mean imputation) and option cost pricing are used. http://laborsta.ilo.org/applv8/data/SSM1_NEW/E/BGR_CPI_Descr... cccccccccccccccccccccccccccccccccccccccccc Bridged Overlap This procedure can be used when the new model and the replaced model are not simultaneously available on the market. The method of bridged overlap uses the average price development within the same product group or the average price development of appropriately equivalent models as a reference. In the producer price index for industrial products, this method can be applied e.g. for adjusting products in the field of mechanical engineering whenever replacement models cannot be found due to small-scale productions or individual manufacture. Especially in cases of product changes in which it is reasonable to assume that also a price change has been taken in addition to changed material or personal costs, the price development of an appropriate comparison group (of models) is used as a substitute. https://www.destatis.de/EN/FactsFigures/NationalEconomyEnvir... ccccccc Imputacja – sztuczne wstawienie pewnych wartości do tabeli danych. Na ogół imputacja jest wykonywana w celu usunięcia tzw. braków danych, czyli wartości nieznanych. Wiele metod statystycznych nie akceptuje bowiem obserwacji z brakami danych. Istnieje wiele różnych metod uzupełniania braków danych (ang. missing data imputation), najprostszą jest zastąpienie braków danych średnią ze wszystkich wartości danej zmiennej w próbce. https://pl.wikipedia.org/wiki/Imputacja |
