Previous applications of ridge analysis to second-order response surfaces based on mixture ingredients (x1; x2; : : : ; xq) which sum to 1 have required transforming from the origin (0; 0; : : : ; 0), which is not in the mixture space, to a point inside the space, most often the centroid (1=q; 1=q;
