Abstract: This paper aims to modelling the evolution of unemployment rate using the Box-. Jenkins methodology during the period 1998-2007 monthly data. The empirical study relieves that the most adequate model for the unemployment rate is ARIMA (2,1,2). Using the model, we forecasts the values of unemployment rate

forecasting and Box-Jenkins forecasting usually refer to the same set of techniques. In this chapter, we will document the running of the ARIMA program. The methodology put forth by Box and Jenkins will be outlined in another chapter, since it uses several time series procedures. ARIMA time series modeling is complex.

[Documentation PDF]. The ARIMA (or Box-Jenkins) method is often used to forecast time series of medium (N over 50) to long lengths. It requires the forecaster to be highly trained in selecting the appropriate model. The Automatic ARMA automates the ARIMA forecasting process using a series of algorithms to select the
Applying the Box-Jenkins methodology, this paper emphasizes how to identify an appropriate time series model by matching behaviors of the sample autocorrelation function (ACF) and partial autocorrelation function (PACF) to the theoretical autocorrelation functions. In addition to model identification, the paper examines

Box - Jenkins Analysis refers to a systematic method of identifying, fitting, checking, and using integrated autoregressive, moving average (ARIMA) time series models. The method is appropriate for time series of medium to long length (at least 50 observations). In this chapter we will present an overview of the Box-Jenkins

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.
