2.2.4.1.2 Algorithm for Moving Average

Moving Average

Moving average calcualtes the mean of the $m$ consecutive data as the smoothed value.

$\hat{y_t} = \frac{1}{m} \sum_{i=t-m+1}^{t}y_i$

$\hat{y_t} = \frac{1}{m} \sum_{i=t-\frac{m-1}{2}}^{t+\frac{m-1}{2}}y_i$

$\hat{y_t} = \frac{1}{2}[ \frac{1}{m} \sum_{i=t-\frac{m}{2}}^{t+\frac{m}{2}-1}y_i + \frac{1}{m} \sum_{i=t-\frac{m}{2}+1}^{t+\frac{m}{2}}y_i]$
