ЗАСТОСУВАННЯ ПОВОРОТУ КООРДИНАТ ДЛЯ ПОБУДОВИ НЕЛІНІЙНОЇ РЕГРЕСІЇ З УРАХУВАННЯМ НЕПЕВНОСТІ ОБОХ ВЕЛИЧИН
Journal Title: Вимірювальна техніка та метрологія - Year 2009, Vol 1, Issue 70
Abstract
In the paper the new method of constructing the nonlinear regression based on rotation of coordinates is proposed and analyzed. In proposed method the uncertainties of both (input and output) quantities are considered. The tangent of rotation angle is equal to the ratio of input to output value uncertainties. Parameters of this regression are determined after three steps: 1- rotation experimental points on the determined angle; 2- using the least squares method to the calculation of regression parameters; 3- determination regression described in original coordinates using inverse rotation.
