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 ...

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 ...

In recent years, there has been increasing interest in the study of asymmetrical fractional factorial designs. Various new optimality criteria have been proposed from different principles for design ...

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 ...

The Annals of Statistics publishes research papers of the highest quality reflecting the many facets of contemporary statistics. Primary emphasis is placed on importance and originality, not on ...

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 ...
