WebThe pseudo-additive model continues the convention of the multiplicative model to have both the seasonal factor S t and the irregular factor I t centred around one. Therefore we need to subtract one from S t and I t to ensure that the terms T t x (S t - 1) and T t x (I t - 1) are centred around zero. These terms can be interpreted as the additive seasonal and … WebA time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus, it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones ...
