In time series analysis, the Box–Jenkins method, named after the statisticians George Box and Gwilym Jenkins, applies autoregressive moving average (ARMA) or autoregressive integrated moving average (ARIMA) models to find the best fit of a time-series model to past values of a time series. See more The original model uses an iterative three-stage modeling approach: 1. Model identification and model selection: making sure that the variables are stationary, identifying seasonality in the dependent series … See more Estimating the parameters for Box–Jenkins models involves numerically approximating the solutions of nonlinear equations. For this reason, it is common to use statistical software designed to handle to the approach – virtually all modern statistical packages … See more • Beveridge, S.; Oickle, C.
