Answers

Here are the answers to the previous questions:

  1. The data needs autocorrelation. We use the chart and the Durbin-Watson statistical test to prove it.
  2. We multiply the trending line of the regression model by the seasonal irregularity.
  3. To smooth the cyclical seasonal data movements. With this value, we can calculate the cycling season of the trending line.
  4. Use the elements of the error to research whether the data has a cyclical trend that could indicate an autocorrelation relationship.
