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 ...

The ADXFF file contains five macros and the ADXFFD SAS data set. These macros are used to construct and manipulate orthogonal fractional factorial designs for two-level factors. Two kinds of ...

ds is the name of the output data set for the constructed design. This data set contains variables for design factors and for a block factor, if the design uses blocking. Default names are used. The ...

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 ...
