Experimental design in which the response is modelled in terms of one or more factor levels.
Notes:
- Response surface methodology is usually associated with optimization. The model used is typically a quadratic function leading to a maximum or minimum response in the factor space.
- The term "surface" implies two factors and a single response, when a plot of the modelled response as a function of values of the factors leads to a surface in the three-dimensional space. This can be generalized to any number of factors.
