Experimentation is a vital part of the scientific method. Most problems in science require observation of the system at work and experimentation to elucidate information about how the system works. In ...

Since 1965 almost all of the contributions to the design and analysis of factorial experiments have involved fractional factorial plans. These contributions may be categorized by three main classes of ...

Space-filling designs such as Latin hypercube designs (LHDs) are widely used in computer experiments. However, finding an optimal LHD with good space-filling properties is computationally cumbersome.

Ethics committees and funding agencies often receive protocols that involve either too many or too few animals to answer the specific research question being investigated. It is evident that a greater ...

The previous example illustrates a complete factorial experiment involving eight runs and three factors: cutting speed (SPEED), feed rate (FEED), and tool angle (ANGLE). Now, suppose two machines (A ...

Methods for designing and analyzing industrial experiments. Blocking; randomization; multiple regression; factorial and fractional factorial experiments; response surface methodology; Taguchi’s robust ...

Applying current principals to traditional factorial designs. Plackett–Burman (PB) designs are a class of fractional factorial designs first developed by two ...
