Fractional polynomial models for constrained mixture experiments
A new - parsimonious but flexible - class of non-linear models, based on Fractional Polynomials, is proposed for fitting the data from constrained mixture experiments. These Mixture Fractional Polynomial (MFP) Models are easily fitted by nonlinear least squares using a partially linear algorithm. They are compared with the recently proposed class of nonlinear General Blending Models, and with several commonly used linear models from the literature. It is shown that the new class of MFP Models outperforms those competing models in several practical applications.

Abstract

A new - parsimonious but flexible - class of non-linear models, based on Fractional Polynomials, is proposed for fitting the data from constrained mixture experiments. These Mixture Fractional Polynomial (MFP) Models are easily fitted by nonlinear least squares using a partially linear algorithm. They are compared with the recently proposed class of nonlinear General Blending Models, and with several commonly used linear models from the literature. It is shown that the new class of MFP Models outperforms those competing models in several practical applications.
