Ref. sobre "smoothing":
Smoothing

Smoothing techniques are used to reduce irregularities (random fluctuations) in time series data. They provide a clearer view of the true underlying behaviour of the series.

In some time series, seasonal variation is so strong it obscures any trends or cycles which are very important for the understanding of the process being observed. Smoothing can remove seasonality and makes long term fluctuations in the series stand out more clearly.

The most common type of smoothing technique is moving average smoothing although others do exist. Since the type of seasonality will vary from series to series, so must the type of smoothing.
