Meaning

A canonical parameterization for linear-mixture score construction remains to be developed.

Statement

Derive numerically stable score coordinates for simplex fractions, reference-component coordinates, unconstrained local coordinates, and extended yields; clarify D invariance and Ds POI/nuisance transformations.

The question in full

Canonical parameterization for linear mixtures

For mixture fractions and extended yields, derive numerically stable score coordinates under simplex constraints, reference-component coordinates, unconstrained local coordinates, and yield parameterization. Clarify D invariance and $D_s$ POI/nuisance transformations.
