Through the plot above, the dark line that is blue the exponential smoothing of that time series making use of a smoothing element of 0.3, as the orange line uses a smoothing element of 0.05.

Through the plot above, the dark line that is blue the exponential smoothing of that time series making use of a smoothing element of 0.3, as the orange line uses a smoothing element of 0.05.

As you care able to see, small the smoothing element, the smoother the time show would be. This will make sense, because given that smoothing element approaches 0, we approach the moving average model.

Double exponential smoothing

Double smoothing that is exponential utilized when there is a trend within the time show. If that’s the case, we make use of this strategy, that will be just a recursive usage of exponential smoothing twice.

Right here, beta could be the trend smoothing factor, plus it takes values between 0 and 1.

Below, you can view just how various values of alpha and beta affect the design of this right time show.

Tripe smoothing that is exponential

This technique extends dual exponential smoothing, with the addition of a seasonal smoothing factor. Continue reading
