[When] using exponential smoothing models for forecasting, it is very important to know the salient characteristics of the time series...(i. e. trend and seasonality among other characteristics) before [choosing an] exponential smoother. The better the diagnosis of the salient characteristics of the time series, the more accurate the exponential smoothing forecasts are likely to be.  3, record 1, English, - exponential%20smoothing%20forecast

For Winters’ method and seasonal exponential smoothing, a seasonal weight near one implies that a nonseasonal model may be more appropriate and a seasonal weight near zero implies that deterministic seasonal factors may be present.  2, record 2, English, - seasonal%20exponential%20smoothing

Soit une famille de points de coordonnées [énumérés] dans un plan rapporté à un repère cartésien. On appelle lissage de ces points par une courbe algébrique de degré k la recherche d'une fonction polynôme P de degré k telle que la courbe d'équation y = P(x) passe «le plus près possible» des [points énumérés].  2, record 4, French, - fonction%20de%20lissage
