I am familiar with how to calculate the autocovariance functions of an AR (2) model, but I am not sure how I to go about calculating the autocovariance and partial autocorrelation functions of an AR (2) model such as Xt = aXt−2 +et X t = a X t − 2 + e t where |a| < 1 | a | < 1.

Share. Cite. Followtion (ACVF) and we often write γX(τ) or just γ(τ) when it is clear which TS it refers to. Note that γ(0) = var(Xt), that is, the variance is constant for all t. Remark 4.3. Similarly, we define so called autocorrelation function (ACF) as ρX(τ) = γX(τ) γX(0) = corr(Xt+τ,Xt) for all t,τ. (4.2) Example 4.1. i.i.d. noise

In Week 1, we learned an autoregressive term in a time series model for the variable x t is a lagged value of x t. For instance, a lag 1 autoregressive term is x t − 1 (multiplied by a coefficient).

Mean, Autocovariance, Stationarity A time series {Xt} has mean function µt = E[Xt] and autocovariance function γX(t+h,t) = Cov(Xt+h,Xt) = E[(Xt+h −µt+h)(Xt − µt)]. It is stationary if both are independent of t. Then we write γX(h) = γX(h,0). The autocorrelation function (ACF) is
