Simple exponential smoothing is a weighted average between the most recent observation and the most recent forecasting, with weights \alpha and 1 - \alpha, respectively.To be precise, the smoothing equation of single exponential smoothing (constant model, trend = 1) is given by level[t] = \alpha *x[t] + (1 - \alpha)*level[t-1],
