Generate n = 100 observations from the autoregression

    1. (a) Generate n = 100 observations from the autoregression

x t = − . 9 x t − 2 + w t

with σ w = 1, using the method described in Example 1.10. Next, apply the moving average filter

v t = ( x t + x t − 1 + x t − 2 + x t − 3 ) / 4

to x t , the data you generated. Now plot x t as a line and superim- pose v t as a dashed line. Comment on the behavior of x t and how applying the moving average filter changes that behavior.

  1. Repeat (a) but with

x t = cos(2 πt/ 4) .

  1. Repeat (b) but with added N(0 , 1) noise,

x t = cos(2 πt/ 4) + w t .

  1. Compare and contrast (a)–(c).
