What Is an Autoregressive Model? A statistical model is autoregressive if it predicts future values based on past values. For example, an autoregressive model might seek to predict a stock's future prices based on its past performance.

What is AR model used for?
AR (Auto-Regressive) Model
This kind of model calculates the regression of past time series and calculates the present or future values in the series in know as Auto Regression (AR) model.
What is an autoregressive time series model?
Autoregression is a time series model that uses observations from previous time steps as input to a regression equation to predict the value at the next time step. It is a very simple idea that can result in accurate forecasts on a range of time series problems.
Which model is an autoregressive model?
AR(p) Models. An AR(p) model is an autoregressive model where specific lagged values of yt are used as predictor variables.
Is AR model a regression?
AR models are linear regression models where the outcome variable (Y) at some point of time is directly related to the predictor variable (X).
