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).tion (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.

Remark 1.2.1. If (Xt: t ∈ T) ( X t: t ∈ T)) is a strictly stationary stochastic process with finite second moments, then it is also weakly stationary. The converse is not necessarily true. If (Xt: t ∈ T) ( X t: t ∈ T), however, is weakly stationary and Gaussian, then it is also strictly stationary.
