Damping factor exponential smoothing
WebExponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. WebExponential Smoothing - Choice of α • Large values of α give greater weight to more recent data (like small N in moving average) – greater sensitivity to variation. • Forecasts will react quickly to shifts in the demand pattern, but more variation in forecasts from period to period. • Small values of the smoothing constant α give greater weight to historical data …

Damping factors are used to smooth out the graph and take on a value between 0 and 1. Technically, the damping factor is 1 minus the alpha level (1 – α). But all you really need to know is smaller alpha levels (i.e. larger … See more Exponential smoothing of time series data assigns exponentially decreasing weights for newest to oldest observations. In other words, the older the data, the less priority (“weight”) the data is … See more The basic formula is: St = αyt-1 + (1 – α) St-1 Where: 1. α = the smoothing constant, a value from 0 to 1. When α is close to zero, smoothing happens more slowly.
