 Mar17 awarded Editor Mar17 comment Is there a reliable recursive formula for a simple moving average (moving mean)? Yes, you was right. Just corrected it. Mar17 revised Is there a reliable recursive formula for a simple moving average (moving mean)? added 7 characters in body Mar16 comment Is there a reliable recursive formula for a simple moving average (moving mean)? The possible reason might be the following. If the values of y(t) are relatively small and w is big, divisions for sum(y(t))/w and (y(t)+y(t-w))/w have different precision orders. (for example if y(t) is approximately 0.001, and n is 10000, division 0.001/10000 is less accurate, compared to 10/10000). Then if you add real numbers with different precisions, the smaller one is truncated.
