NOTE.—With fixed-weighted indexes, real gross product
is obtained by the double-deflation method as the difference between real gross
output and real intermediate inputs. For the benchmark-years-weighted quantity
index, the following relationship was used to obtain the gross product index:
(I_{GPO})^{\theta_2} = {I_{GO}}/{(I_{II})^{\theta_1}}$, where *I_{GPO}* is
the derived benchmark-years-weighted index of gross product, *I_{GO}* is a
benchmark-years-weighted quantity index of gross output, *I_{II}* is a
benchmark-years-weighted quantity index of intermediate input, and *\theta_1*
and *\theta_2* are the average current-dollar shares of gross output
accounted for by intermediate inputs and value added. Use of this relationship
provides a close approximation to a benchmark-years-weighted quantity index.
