Special cubic model for multiple regression in triangular coordinates

Докладчик: Kolarević M.

This article presents methodology of a multiple regression calculation in triangular coordinates. Presented methodology includes: the equation of theoretical regression model, procedure of regression coefficients determination using the least square method, check procedure for the adequacy of mathematical models, evaluation of significance of regression analysis coeffcient, calculation of confidence limits of regression coefficients. Graphical representation of a mathematical model in the using triangular contour and surface diagram is also shown.
