ABSTRACT

The Box-Jenkins methodology was used to select an ARMA model to forecast beef production in Baja California, Mexico. The series of bovine carcasses processed monthly in !he state's slaughterhouses between 2003 and 2010 was used. Because the inspection of the series graph and correlogram did not determine a stationary behavior, an augmented Dickey-Fuller test was pertormed and it was found that the series was stationary. As a result of identification procedure, an AR (1) andan ARMA (2, 1) models were selected and estimated using ordinary least squares. The estimated models were compared using the significance of the regression coefficient and the Akaike information and Schwartz Bayesian criteria. A diagnostic check was done examining the goodness of fit of the models by plotting the residuals; the Q statistic was used to test for autocorrelation. Because the results were similar, a predictive efficacy evaluation of two models was carried out using a group of forecast error statistics. The result of these tests indicated that the ARMA (2, 1) had a better forecasting capability, this was supported by plotting together a forecasted series with the actual series and the out-of sample prediction for January of 2011. The results support the use of ARMA models to obtain reliable short term forecasts of beef production in Baja California.
