Abstract: AR model is a widely used model in mathematical statistics, forecasts and other fields such as the economy, transportation, information, natural phenomena. The parameter estimation is an important process to establish the AR model. This paper uses AR model as the research object, and introduces four methods to estimate the parameters of the AR model.
