Which of the following statements about the model you fit are true?

Question

Answer

Goodness-of-fit (e.g. R 2 ) to the existing data indicates how well the model will extrapolate data

Answer

Answer

Answer

Using fewer years of data to fit the model will improve performance if the true underlying model changes over time.
