1. For the MA(1) process X t Zt 0.5Zt 1
1)
Determine whether this process is invertible
X t (1 0.5B) Zt
1 0.5B 0
B 2, B 1
So this process is invertible
2)
If invertible, please write this process as A
1. According to the joint distribution of X and Y, We can get the joint distribution of X-Y and X+Y.
Assume U=X-Y, V=X+Y. P(U) and P(V) are the marginal distributions.
