Expert Answer
Exponential smoothing is ideal when the time series is free of seasonal or trend components and results in forecasts that exceed actual results when the time series exhibits a decreasing linear trend or shows a forecasts that trail actual results when the time series exhibits an increasing trend.
The single exponential smoothing can be calculated as;
Y’_{t+1} =alpha Y_{t} + (1-alpha )Y’_{t}
where Y’ t+1 represents the forecast value for period
