ABSTRACT: This paper presents the review for the Seemingly Unrelated Regression Equation (SUR) or system model involved several individual relationships that related by their disturbances terms are correlated. This model appears in the beginning of the sixties of the last century, initially introduced by Zellner (1962, 1963), and followed many author .the model has been applied in many fields such as econometric, analysis of economic phenomenon such as, investment, income, consumption, demand functions. We review comprehensively the estimators for (SUR) equation models whereas there are many author write about this model and some properties of the estimators.
