17.8. Prediction of Properties of Blends

Polynomial curve fitting method is also a good approach to estimate the properties of other blends. This method is an attempt to describe the relationship between variable X as a function of available data and a response Y, which seeks to find a smooth curve that best fits the data. Mathematically, a polynomial of order k in X is expressed in the following form [1,17,50,51,72–74]:
