(analogous to the error terms included in various types of statistical models). To visually explore a series, time series are often formally partitioned into each of these three components through a procedure referred to as time series decomposition, in which a time series is decomposed into its...
The decomposition of time series is a statistical task that deconstructs a time series into several components, each representing one of the underlying categories of patterns. When we decompose a time series into components, we think of a time series as comprising three components: a trend componen...
