WebbTheoretical variance of AR (1) process From the model equation z t = β 0 + β 1 z t − 1 + a t, V a r ( z t) = V a r ( β 1 2 z t − 1 + a t) = β 1 2 V a r ( z t − 1) + σ a 2. Since z t − 1 is by definition uncorrelated with a t, the innovation at time t and by stationarity V a r ( z t) = V a r ( z t − 1) = σ z 2. Hence, σ z 2 = σ a 2 1 − β 1 2 .
