Single exponential smoothing with trend: single smoothing (short for single exponential smoothing) is not very good when there is a trend the single coefficient \(\alpha\) : is not enough sample data set with trend. Double exponential smoothing double exponential smoothing computes a trend equation through the data using a special weighting function that the smoothing constant(s determines how fast the exponential smoothing - trend.
