Autoregressive Models. A first-order autoregressive model (AR (1)) with normal noise takes each point yn y n in a sequence y y to be generated according to. yn ∼ normal(α+βyn−1,σ). y n ∼ n o r m a l ( α + β y n − 1, σ). That is, the expected value of yn y n is α+βyn−1 α + β y n − 1, with noise scaled as σ σ. business names registration act 2011 austlii

WebWhy is unit root troublesome? • For one thing, the law of large number (LLN) does not hold for a unit root process. • For a stationary and ergodic process LLN states that as T → ∞ 1 T ∑T t=1 yt → E(yt) • Unit root may cause three troubles. First, E(yt) may not be a constant. Second, the variance of yt is non-constant.
