Math::EMA - compute the exponential moving average

1 ++

1 ++

This module computes an exponential moving average by the following formula avg(n+1) = (1 - alpha) * new_value + alpha * avg(n) where alpha is a number between 0 and 1. That means a new value influences the average with a certain weight (1-alpha). Th...
