Description: example if yt is from the following model yt 05 yt 1 02 yt 2 et et 1 et wn01 1 express yt fyt 1 vt vt ut 0 ut et et 1 2 is yt stationary check the eigenvalues of f 3 express yt et y1 et 1 y2 34235

          Example
If {Yt} is from the following model
Yt = 0.5 Yt-1 + 0.2 Yt-2 + Et - Et-1  Et ~WN(0.1).
(1) Express Yt = FYt-1 + Vt. Vt = 
[Ut]
0
Ut = Et - Et-1
(2) Is {Yt} stationary (check the eigenvalues of F)
(3) Express Yt = Et + Y1 Et-1 + Y2 Et-2 + ... Give Y1 value.
(4) Write the relations between Y(0), Y(1), Y(2).
