WHAT IS A TIME SERIES? ... An observed time series can be decomposed into three components: the trend (long term direction), the seasonal (systematic, calendar related movements) and the irregular (unsystematic, short term fluctuations).

Answer 2

The trend component can be calculated with the help of Frequency.

• The concept of trend analysis is to calculate or estimate future demand based on historical data and current data.
• When the time period and frequency of data occurrence for a specific subject are indicated or expressed, this can be estimated.
• If the frequency is high in a certain time period, the frequency data will show a stronger trend and vice versa.
• As a result, the frequency data can be used to compute the trend component of a time series.
