The ADX Interface for Design and Analysis of Experiments

Canonical and Ridge Analysis

Canonical analysis can be performed to determine the shape of the fitted response and determine if the estimated stationary point is a maximum, minimum, or saddle point. This type of analysis can be used to answer the following questions:

Is the surface shaped like a hill, a valley, a saddle surface, or a flat surface?
If there is a unique optimum combination of factor values, where is it?
To which factor or factors are the predicted responses most sensitive?

Ridge analysis can be performed to determine the direction in which further experimentation should be be conducted.
