CALCULATING AN INDEX THAT REPRESENTS THE PRICE OF A COMMODITY

摘要

An index that represents a price of a commodity paid by a plurality of purchasers is calculated by identifying a first subset of purchasers from the plurality of purchasers. A second subset of purchasers is selected from the first subset of purchasers, prices are obtained from the purchasers that comprise the second subset, and a statistic of the prices is calculated to develop the index.
