To estimate an interaction effect we need more than one observation for each combination of factors. Factor A has K levels Factor B has J levels.

. SOCR ANOVA Activity 页面存档备份存于互联网档案馆 and interactive applet 页面存档备份存于互联网档案馆. In a typical situation our total number of runs is N 2k-p which is a fraction of the total number of treatments. A design with 9 factors requires 512 runs.

The number of runs necessary for a 2-level full factorial design is 2 k where k is the number of factors. Examples of all ANOVA and ANCOVA models with up to three treatment factors including randomized block split plot repeated measures and Latin squares and their analysis in R 页面存档备份存于互联网档. For example a 2-level full factorial design with 6 factors requires 64 runs.

26 Full PDFs related to this paper. A short summary of this paper. A fractional factorial design is useful when we cant afford even one full replicate of the full factorial design.

In a factorial design one obtains data at every combination of the levels. Using our example above where k 3 p 1 therefore N 22 4 So in this case either one of these blocks above is a one half fraction. It is our belief that the two-level factorial and fractional factorial designs should be the cornerstone of industrial.

The 2 k and 3 k experiments are special cases of factorial designs. As the number of factors in a 2-level factorial design increases the number of runs necessary to do a full factorial design increases quickly.
