A methodology for forming the regression model of ternary system

Abstract

This paper presents a methodology of multiple regression analysis of three-component systems. There are several stages: 1) calculation of the parameters of regression models, 2) checking the adequacy of mathematical models, 3) selection of regression model, 4) assessment of the significance of model parameters, 5) calculation of confidence limits of regression coefficients and 6) graphical representation of a mathematical model with the triangular surface plots or contour plots.
