A Device for the Smoothing of Time Series
Walter A. Hendricks, Hendricks, Walter A. · RePEc: Research Papers in Economics · 1959
When sample estimates are plotted in time series, part of the irregularity displayed by the plotted points is chargeable to sampling errors in the individual estimates. This paper describes a method for smoothing the series to eliminate effects of the sampling errors. Fluctuations that can be ascribed legitimately to actual changes in the "true" values are retained.
