### Handelsdaten Legende | Term | Description | | :---------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Base Year /Period | The year /period in which volume series are expressed using the value of the average prices. | | CP | Current price. | | | Estimates valued in the prices of the period when the activity occurred. Also referred to as “Nominal Prices”. | | CVM | Chained volume measure. | | | The result of joining together two indices that overlap in one period by rescaling one of them to make its value equal to that of the other in the same period, thus combining them into single time series. Also referred to as “Chain-Linked Values”. | | CVMRE | Chained volume measure that has been re-referenced to a reference year distinct from the last base year. | | | A volume measure obtained by chain linking. | | CYP | Current year's prices. | | | The average price in the year in which the activity took place. | | Deflator | A price index. | | | By applying the deflator to a current price series the associated volume measure series may be calculated. | | Fixed Base Index | An index which uses fixed weights from the defined base period for all component index numbers. | | KP | Constant Price Series (KP). | | | Term referring to expressing values in terms of a base period. A volume also known as constant prices or real growth. Calculated directly or indirectly by dividing current price value by the deflator (price index). In effect you are holding the prices constant in the base period or removing the effect of price change. | | Last base year | This is the last year in a Chained Volume Measure Series which is used as a base year. | | | In the last base year annual CP value = annual KP value. | | NSA | Non-seasonally adjusted. | | PYP | Previous year's prices. | | | The average price in the year preceding the period in which the activity took place. The series derived from multiplying the volume series in the current period, by the average price of the previous year. This process is also known as unchaining. Previous Years Prices are additive and are the method by which volume series can be aggregated together. | | PYP* | Previous year's prices that are consistent with the re-referenced CVM and the tail are genuine previous year's prices. | | Reference period | The reference period is the period for which an index series is set equal to 100 or the period for which a volume index series may be set equal to the current price value in order to express the index series in terms of currency units. In the reference year, the implied deflator is equal to 1, and series are additive. | | SA | Seasonally Adjusted. | | | Seasonal adjustment aids interpretation by removing effects associated with the time of the year or the arrangement of the calendar, which could obscure movements of interest. | | Volume Index | At the elementary level (that is, detailed disaggregated level) a volume index is most commonly presented as a weighted average of the proportionate changes in the quantities of a specified set of goods or services between two periods of time. In a volume measure, the estimates for all periods are in the same price. | | VM | Volume measure. |
