Example of a Half-Fraction Factorial Design See FACTEX3 in the SAS/QC Sample Library: Often you do not have the resources for a full factorial design. In this case, a fractional factorial design is a ...

In our coating example, we would call this design a 2-level, 3-factor full factorial DOE. The number of runs would then be ...

Fractional Factorial Design Macros: ADXFF File The ADXFF file contains five macros and the ADXFFD SAS data set. These macros are used to construct and manipulate orthogonal fractional factorial ...
