Tiivistelmä: | The authors consider decompositions of financial time series that identify important modes of variation in the series. The first term in the decomposition measures long-term trends and focuses on large-scale features of variability. The second term measures short-term trends and local features of variability remaining after the long-term trend has been removed. The third term measures the irregularity left in the series after the long- and short-term trends have been subtracted. |
