## How do you find the order of a moving average?

A moving average of order m can be written as ^Tt=1mk∑j=−kyt+j,(6.1) (6.1) T ^ t = 1 m ∑ j = − k k y t + j , where m=2k+1 m = 2 k + 1 . That is, the estimate of the trend-cycle at time t is obtained by averaging values of the time series within k periods of t .

## What is the simple moving average?
