A Set of End Weights to End All End Weights
A Set of End Weights to End All End Weights
Introduction
Given a moving average used to calculate a seasonal factor curve or a trend-cycle curve, the problem is to derive a set of moving average weights for the end terms which will minimize revisions between preliminary and final estimates of the seasonal or trend-cycle. As an example, consider the end weights for the 5-term moving average as a seasonal factor curve. End weights for other seasonal curves of different length and trend-cycle curves may be derived in a similar manner.
