Answer: inflation
Explanation: Inflation is an increase in the general level of prices or in the cost of living and is not a part of the major components of a time series which is defined as a set of data points, each of which represents the value of the same variable at different times, normally at uniform intervals. It consists of: seasonal variations (repeats over a specific period), trend variations (moves up or down in a reasonably predictable pattern), cyclical variations (corresponds with economic cycles or which sometimes follow their own peculiar cycles), and random variations that do not fall under any of the above classes.
