WebRecall from Lesson 1.1, that the 1 st order autoregression model is denoted as AR (1). In this model, the value of x at time t is a linear function of the value of x at time t − 1. The algebraic expression of the model is as follows: x t = δ + ϕ 1 x t − 1 + w t. One example in Lesson 1.1 and Lesson 1.2 concerned the annual number of … WebAn AR(1) model, on the other hand, would show a PACF that was zero for lags of 2 or more and an AR(2) model would have a PACF that was zero for lags of 3 or more.
