Plackettburman and boxbehnken designs as chemometric tools. To maintain rotatability, the value of \ \alpha \ depends on the number of experimental runs in the factorial portion of the central composite design. Each factor, or independent variable, is placed at one of three equally spaced values, usually coded as. Compared with central composite design, bbd is often considered to be more relatively efficient. Experimental design boxbehnken design bbd is one of the most common designs used in the response surface measurment rsm, which is a class of rotatable or nearly rotatable secondorder designs based on threelevel incomplete factorial designs. Lactoglobulin were investigated using antioxidant indexes and spectroscopy techniques. That is, the question is whether or not the design is divided into blocks such that the block effects do not affect the estimates of the coefficients in the second order model.
