WebAug 23, 2024 · Singular spectrum analysis (SSA) aims at decomposing the observed time series into the sum of a small number of independent and interpretable components such as a slowly varying trend, oscillatory components, and noise (Elsner and Tsonis 1996; Golyandina et al. 2001).SSA can be used, for example, for finding trends and seasonal …
WebDec 23, 2024 · Singular Spectrum Analysis (SSA), a relatively new but effective approach in time series analysis, has been devised and widely used in various of practical problems in the recent years. It is regarded as PCA for time series how-ever has huge advantages over it. SSA will surely become a principal time series analysis method in the future. WebJan 24, 2024 · Circulant SSA is a new variant of SSA that allows to extract the signal associated to any frequency specied beforehand.
