Time Series: Autoregressive models AR, MA, ARMA, ARIMA
people.cs.pitt.eduThe procedure of using known data values to t a time series with suitable model and estimating the corresponding parameters. It comprises methods that attempt to understand the nature of the time series and is often useful for future forecasting and simulation. There are several ways to build time series forecasting models,

In time-series analysis, autoregressive integrated moving average (ARIMA) and its variants are one of the most consolidated approaches based on classical statistics[Ahmed and Cook, 1979; Williams and Hoel, 2003]. However, this type of model is limited by the stationary assumption of time sequences
