Question
Q2C. Considering the following MA(3) process: y_t = u_t − 0.7u_(t-1) − 0.2u_(t-2) + 0.4u_(t-3) Where u_t is a white noise process with variance equal to 1. What is the value epsilon_k = cov(y_t,y_(t-k)) for k = 0? Provide the correct answer along with the working steps and underlying assumptions used to calculate the value of epsilon_k = cov(y_t,y_(t-k)) for k = 0.
