utilize self-evident logic and take advantage of the fact that, most often, the future is founded on the past.
Although there are no hard-and-fast rules, it seems that most engineers are basically extrapolators
, most pure scientists are primarily pattern analysts, and most marketing people are goal analysts.
BEA adjusts the monthly extrapolator
to account for the difference in coverage between the QCEW-based data and the CES-based data.
Source Data and Methods for Current-Dollar GDP and Current-Dollar GDI Annual estimates: Source data and methods used to Component determine level for benchmark and other years or used to prepare an extrapolator
or interpolator Gross domestic product of $11,734.
As a result, a significantly smaller share of the early estimates for GDP is based on trend extrapolators
rather than directly on source data.
5) Zaluar's evolutionism, as has been discussed above, drank from a range of sources from the eighteenth century through Darwin and his early disciples and extrapolators
, and it was heavily tinged by Zaluar's Christian beliefs (for the most specific references to terrestrial evolution in Doutor Benignus see 202 and 278-82).
Interpolators and extrapolators
are based on shipments and inventory-change data from the Bureau of the Census Annual Survey of Manufacturers and the 1996 annual input-output tables.
BLS has recently completed research into performing the extrapolation with various time series modeling techniques, including regression and ARIMA models, as a substitute for the UI-universe-based extrapolators
currently used, and found some improvement in results.
for these estimates are prepared using a wide array of source data, including surveys from the Census Bureau, the Bureau of Labor Statistics, and other public and private sources.
However, the review may also consider the latest tabulations of the benchmark UI data for past quarters and how well the extrapolators
have tracked them, as well as other related indicators, such as tax collections data from the Treasury Department or movements in the Labor Department's Employment Cost Index.
