Web24 mrt. 2024 · Hint: "method of moments" means you set sample moments equal to population/theoretical moments. For example, the first sample moment is X ¯ = n − 1 ∑ i = 1 n X i, and the second sample moment is n − 1 ∑ i = 1 n X i 2. In general, the k th sample moment is n − 1 ∑ i = 1 n X i k, for some integer k. The first population moment is E ... Web3 feb. 2024 · The method of moments estimator for AR processes can be had with the Yule-Walker equations. But how is it derived? The equation for AR (1): Y t = a Y t − 1 + ϵ t Where ϵ ~ N ( 0, σ 2). So the moment conditions are E ( ϵ) = 0, E ( ϵ 2) = σ 2 But the "standard" solution can't be used as E ( ϵ) = E ( Y t − a Y t − 1) = 0 is true for any a.
