Problem 4 信号和系统考试代写
Assume that the demand for a product in an inventory, z(k). Can be described as z(k) = 300 + 10k + y(k) where the time unit is days. And y(k) is described by the process y(k)−0.7y(k−1)−0.ly(k−2) = 6e(k) where e(k) is white noise with zero mean and unit variance. Make a prediction for the demand and determine the expected standard deviation of the prediction error for days eight, nine. Ten and eleven when the data for previous days are given by z(7) = 375, z(6) = 370, z(5) = 350, z(4) = 330, z(3) = 325, z(2) = 320, z(1) = 320, y(7) = 5, y(6) = 10. 信号和系统考试代写
