Worked example

What does “time series” mean in Time Series and Forecasting?

  1. 1Use the wording this chapter gives for time series.
  2. 2The book says: data that has a time component, or an ordered sequence of data points.
  3. 3Do not use the meaning of forecasting. That term means making predictions about future, unknown values of a time series.

Result: data that has a time component, or an ordered sequence of data points

Why. That is the meaning this chapter gives for time series.

Do not swap time series and forecasting. time series means data that has a time component, or an ordered sequence of data points. forecasting means making predictions about future, unknown values of a time series.
