Abstract
A problem that economic statisticians frequently face is to estimate the true movement in a time series on the basis of two or more imperfect indicators. A well-known example is nonagricultural employment as indicated (a) by a monthly survey of households and (b) by a monthly survey of employers. This article describes a procedure for estimating true changes in a time series as a linear combination of two indicators, with weights for indicators chosen so as to minimize errors. It applies the procedure to two examples, nonagricultural employment and capital goods prices.Keywords
