Triple Exponential Smoothing

On this page you will see a description and an example of a triple exponential smoothing.

If you skip the origins of this method, and move directly to the calculations, it is possible to express the triple exponential smoothing:

The general equation is as follows:

Smoothing the trend is as follows:

Smoothing seasonality as follows:

The forecast can be expressed as:

Where,

- A simple value within the range [0, 1]

y - simple observation

S - smoothed value monitoring

b - KOF. trends

I - seasonality index (year, month)

F - forecast by m periods ahead

t - index of current observations
