Question 4 - (10 marks) Seasonality and the function accuracy () (a) Fit a Holt's Linear (with no damping parameter), a Holt-Winters additive and a Holt-Winters multiplicative model to the New Zealand Consumer price index (CPI) from the data set global economy. Then, compare their in-sample accuracy with the function accuracy (). The output will return a Nal for the Holt-Winters models. Why is this happening?
