Questions
Factual
- How would you compare the results of the different models and forecasts to select the appropriate constraints?
- In the initial plot of the river data, is there something that could be used to foresee the seasonality and/or trend immediately without breaking into components?
When, how, and why?
- While the automated selection provided ARIMA values, how would you select the different parameters?
- How would you decide on the different modeling techniques used for your dataset?
Challenges
- Several of the forecasts involved negative values for the river flow. How can that be avoided?
- Either use a time series that you have available or find one that has the components addressed in the chapter and apply the analysis available in R.
