Tables of fractional factorial designs for factors with three or five quantitative levels are presented. Series B (Statistical Methodology) of the Journal of the Royal Statistical Society started out ...

Fractional factorial (FF) designs with minimum aberration are often regarded as the best designs and are commonly used in practice. There are, however, situations in which other designs can meet ...

For example, the following statements list all regular fractions for six factors with either less than 80 runs or exactly 8 blocks: %adxgen %adxff %adxpff ( (ntmts=6) & ( (nruns < 80) or (nblks=8))) ...

You use the SIZE statement to specify the size of the design, which is the number of runs in the design. The SIZE statement is required for designs of less than a full replicate (for example, ...
