D Question 3 2 pts [2 marks] Robert decides to estimate an AR(10) model on monthly inflation rate series spanning 10 years. What is the maximum total number of periodicities the fitted model can deliver? 10 D Question 4 2 pts [2 marks] Compute E(1/10 ) for the following model, where & ~ wn(0, 0.16), i.e., a white noise process with mean zero and variance 0.16. Please give the exact answer. 1D Question 3 2 pts [2 marks] Robert decides to estimate an AR(10) model on monthly inflation rate series spanning 10 years.
