Abstract:In the system of two seemingly unrelated nonlinear regression equations, approximate score function and quasi approximate score function are defined. These function have sample information and extra information. Under mean squared error standard, for these functions, the superiority over unrelated score function and quasi unrelated score function are proved.
Keywords:Seemingly unrelated nonlinear regression model  Score functionl Quasi score function
