TL;DR: Experiments with mixtures require a special form of polynomial model called the canonical polynometric model, which is based on the eigenva of the Tournaisian model.
Abstract: Experiments with mixtures require a special form of polynomial model called the canonical polynomial model. Moreover, many mixtures problems are also subject to additional constraints that often cause ill-conditioning, or collinearity. Using the eigenva..
