Simplex centroid design,

Definition of Simplex centroid design:

1. A type of mixture design used to analyze the relationship involved in a process that contains several variables. Simplex centroid design is constructed to form a triangle with data points located at each corner, the three midpoints on each side, as well as the center and is highly effective at demonstrating the significance related to the three primary components. Its an experimental design used to determine the relationship between a variable that impacts the process and resulting response, with each variable altered in a systematic approach.
