Concordant domain of factor

Let us stick to response geometrical interpretation of black box with two input factors. A simple graphic system with x-y coordinates is sufficient for this. One may insert values of variation levels of one factor on one axis, and those of the other factor on another axis. Each black box status will have a corresponding point in the surface. As has been said in Sect. 2.1.3, factors are defined by their domains. This means that each factor is defined by its minimal and maximal values where it may be changed continuously or discontinuously. If the factors are concordant then those limits in the plane form a rectangle within which are the points that coincide with black box statuses. Dashed lines in Fig. 2.28 mark the limit values of the domain of factors and full lines the limits of concordant domain of factors. To present graphically the response values, we use the third axis of the coordinate system, so that the response surface has the shape given in Fig. 2.29.
