Autoregressive Model - What Is It, Formula, Examples

WebIn autoregressive, or AR, models, variables are specified as a function of their own lagged values. An autoregressive order 1 or AR1 contains the previous lagged value for the target variable as an input. AR models are longer memory than moving average models of the same order or with the same number of lags. WebMar 20, 2016 · 19 Mar 2016, 19:58.
