Exponentially Weighted Averages
This technique is used for generating smoother lines that adjust to a graphic. In finances, it is used to predict the overall trend of a graphic. The function that defines the EWA is the one bellow:
Vt = β V(t-1) + (1 - β) θt
Where:
β: Hyperparammeter that we have to adjust.
V(t-1): Value calculated for the previous element of the graphic.
