The four components are:

  • Long-term trends, which describe long-term trends;
  • Seasonal changes, representing seasonal changes;
  • Cyclical fluctuations, which correspond to cyclical rather than seasonal changes;
  • Irregular variation, which is another non-random source of sequence variation.
