FORECAST FOR BRANCH ONION PRODUCTION FROM A VAR MODEL
Main Article Content
Abstract
This work aims to develop a VAR forecasting model for branch onion production with data from the municipality of Aquitania-Boyacá, using multivariate time series methods. The methodology has included the materialization of study phases according to the Box Jenkins method and the application of a series of Phillips and Perron statistical stationarity tests, augmented Dickey-Fuller unit root (ADF), Jarque-Bera normality tests, Phillips Ouliaris test, Granger causality test, among others. The results allow establishing a forecast model under normality, which can support the decision making of technical institutions in the sector. Finally, the conclusions allow establishing the need for this type of models that result in research for the improvement of the agricultural sector in the face of the production and harvested area.
