استعمال انموذج الانحدار الخطي الضبابي في تقدير أثر سعر صرف الدولار على الناتج المحلي الاجمالي في العراق

Abstract EN

The fuzzy linear regression model is one of the statistical methods that are used to represent the relationship between two or more phenomena when those phenomena or some of them are characterized by the inaccuracy or reliability of their data.

The research deals with formulating the fuzzy relationship between the Iraqi GDP and the dollar exchange rate based on a fuzzy linear regression model with fuzzy inputs and outputs, and then using the fuzzy least squares method in estimating the impact of the dollar exchange rate (the explanatory variable) on the GDP (response variable), Since the observations of both variables are represented by fuzzy trigonometric numbers.
