In this question, you are required to show detailed intermediate derivation steps for each sub-question. Omission of intermediate processes could result in the substantial deduction of points. Consider a sequence of independent and identically distributed random variables ut, where t = -1,0,1,2,3,... with a mean of O and a variance of 1. You investigate the following moving average process: 1 1 y = ut -u-1 + 16 Ut-2 (1) Calculate E%) and Var(y). Weight: 8.33%) (2) Calculate Corry,Ye+1), Corr(yt.Yt+2), and Corr(yt.Ye+s), wheres > 2. Weight: 8.33%) (3) Calculate the partial autocorrelation with a lag of 1 (i.e., Tu) and 2 (i.e., T22). Weight: 8.33% (4) Concisely describe the difference between autocorrelation and partial autocorrelation in this moving average process. Weight: 8.33%)
