Its accurate error is lower than the permissible error regulated by the government in feasibility research phrase. Because of the penetrability of its process and normality and objectivity of its results, subjectivities of organizations or individuals can be avoided effectively and different estimators can get almost the same result by using it. Furthermore, its process has stronger persuasiveness than former ones. So it is obvious that the new method is better than former methods and other model predicting methods in similar studies.
