Further Explanation
The TMA is a special case of the WeightedMovingAverage
,
where the term triangular is motivated by the way in which the weights are chosen for the elements of the
time series array. For example, for a 7
-period TMA, that is when the time series has length 7
,
the corresponding weights of the time series elements are: 1
, 2
, 3
, 4
, 3
,
2
, 1
. In the case of the 6
period TMA the weights would be 1
, 2
, 3
,
3
, 2
, 1
.
