Abstract:
في هذا البحث تم ايجاد الانموذج الافضل لانتاجية محصول الرز للمحافظات ( ذي قار - النجف - القادسية - المثنى - ميسان ) خلال المدة ( 1969 - 2014 ) باستعمال نماذج بوكس جنكنز(Box - Jenkins) ومن ثم التنبؤ بانتاجية الرز, حيث تم فحص وتشخيص بيانات السلسلة الزمنية من | The research aims to find the best model the agricultural production of crop for some Iraqi governorates ( Najaf - Qadisiya - Maysan - DhiQar - Muthanna ) during the period ( 1969 - 2014 ) applying Statistical methods used in forecasting time series models as Box - Jenkins method, of tests to identify the existence of stationary,estimation has been studied and included the using of maximum likelihood estimation method, as well as studying the Diagnostic checking using a number of tests to define the scope of models relevancy that has been estimated for the data examined by depend on confidence interval test and Ljung and Box ,then forecasting for the production of rice crop for the years ( 2015 - 2025 ) , chosen for the province of Najaf and Qadisiya is ARIMA ( 1 , 1 , 1 ) , while the model chosen for the provinces ( DhiQar, Muthanna , Maysan ) is the AR ( 1 ) , by depend on Akaike information criterion (AIC), Hannan Quinn information criterion (H - Q),The significance of the estimated parameters of the model.
