Abstract:
تعد دراسات المقارنة بين طرق تقدير المعلمات من الدراسات المهمة التي تاخذ حيزا واسعا في البحوث الاحصائية، لذلك تهدف هذه الدراسة الى اجراء مقارنة من خلال الفترات بين فترة الثقة والفترة البيزية للتركيبة الخطية لمتوسطات عامل التداخل في تصميم متداخل متزن لمرح | A Comparison studies among parameters estimation approaches are important studies that take a large space in statistical searches. So that the purpose of this study is to make a comparison through the intervals between the confidence interval and the Bayesian interval for linear combination of nest factor means in a two stage balanced nested design.The confidence interval was found by using an advance approach in inference called (Mixed Inference), and the Bayesian interval was found by using another approach in inference called (Bayesian Inference), then a comparison was happened between the two intervals (obviously the two kinds of inference).We apply this comparison on a real data experiment represent weights of vetch planet in (1998), and by using simulation. The results of the real data experiment and simulation shows an important conclusion which said that the confidence interval for linear combination of nest factor means is better than the Bayesian interval of the same linear combination for any suggestion confidence coefficient.Finally, An assumption study established to know the causes that leads to that important conclusion
