Components of a time series - IHMC Sample Knowledge …
Components of a time series Any time series can contain some or all of the following components: 1. Trend (T) 2. Cyclical (C) 3. Seasonal (S) 4. Irregular (I) These components may be combined in di erent ways. It is usually assumed that they are multiplied or added, i.e., y t= T C S I y t= T+ C+ S+ I

03 Time series with trend and seasonality components
web.vu.ltTime series with deterministic components Up until now we assumed our time series is generated by a stationary process - either a white noise, an autoregressive, a moving-average or an ARMA process. However, this is not usually the case with real-world data - they are often governed by a (deterministic) trend and they might have (deterministic)
