with A, ER and where {et} {n} are independent white noise
processes with {e} ~ WN(0,0²), and {n} ~ WN(0,02). Find ex-
pressions for the following in terms of model parameters and where
possible use notation of Kronecker-Delta functions:

Expert Solution

Step 1

From the given information,

$X_{t} : = λ + η_{t}$

$Y_{t} : = μ + ε_{t - 1}$

$Z_{t} : = \nabla ε_{t} = ε_{t} - ε_{t - 1}$

where $λ, μ \in ℝ$

$\{ε_{t}\} ~ W N (0, σ^{2})$ and $\{η_{t}\} ~ W N (0, σ_{η}^{2})$

$\{ε_{t}\} a n d \{η_{t}\}$ are independent white noise processes.
