It is an aggregate index that represents the overall level of development of a country or region towards the Knowledge Economy.

Ordinary aggregated indices method allows comprehensive estimation of complex (multi-attribute) objects' quality.

Most elementary aggregate indexes are necessarily 'unweighted' averages for the sample of products within the sampled outlets.

Over all, the fund's bonds have a lower credit rating and higher yield than its benchmark, the Lehman Brothers Aggregate index.

Aggregated index Q value is determined not only by single indices' values but varies depending on non-negative weight-coefficients w(1),.

Quantity indexes are used in computing aggregate indexes for physical "capital" summarizing equipment and structures of different types into one time series.

In the second stage, the elementary indices are combined to create a number of aggregate indices, including the CPI.

(See, for example, Divisia monetary aggregates index.)

The optimists did better last quarter: while the aggregate index was gaining just 2.21 percent, the Treasury portion of the index was up 3.79 percent.

The fund had a total return of 6.1 percent through Sept. 30, outperforming the 5 percent return of the Lehman Aggregate index.

These aggregate indices (including the CPI) are calculated using a Laspeyres index computed as:

In econometrics and official statistics, and particularly in banking, the Divisia monetary aggregates index is an index of money supply.

Aggregated indices randomization method (AIRM)

Often aggregate indices are criticized for their concentration on monetary issues, especially when data on women's income is sparse, and grouping women into one large, undifferentiated mass.

The main advantage of AIRM over other variants of aggregated indices methods is its ability to cope with poor-quality input information.

The looked for average aggregated estimation of objects' quality level may be identified now with mathematical expectation of corresponded random aggregated index Q(I).

Aggregated Indices Randomization Method (AIRM)

The U.S. Federal Reserve Bank of St. Louis computes similar Divisia monetary aggregate indexes.

François Divisia (1889-1964) was a French economist most noted for the Divisia index and the Divisia monetary aggregates index.

Variability over time in aggregate indices of price level, such as the CPI, is often associated with a greater dispersion in relative prices at a point in time.

Thus, for example: Weighted averages of elementary aggregate indexes (e.g. for men's shirts, raincoats, women's dresses, etc.) make up low level indexes (e.g. Outer garments).

In that year, the Lehman Aggregate index, which includes Treasury, corporate, mortgage and agency securities, returned 4.1 percent, well behind the 26.4 percent surge in the Standard & Poor's 500-stock index.

Step 4: Calculating the geometric mean of the arithmetic means for each indicator: Obtain the reference standard by aggregating female and male indices with equal weight, and then aggregating indices across dimensions.

There are two possible ways of computing a weighted aggregate index: first, we can use base-period quantities as weights (the Laspeyres method); secondly, we can use current-period quantities as weights (the Paasche method).

It is well known that the most subtle and delicate stage in a variant of the aggregated indices method is the stage of weights estimation because of usual shortage of information about exact values of weight-coefficients.
