Statistical Index used in Economic Analyses

The index is sensitive to time changes of quantity and price data, over time, drawn from sub-measures, partially additive as they are measured in different units. The index summarizes these in a time series which includes the updates in quantities and prices’ values.Because usually data are not measured in continuous time, it is considered that a series designed as a Divisia index, indicates that the series follows a procedure that makes a close analogue in discrete time periods.
