Section 8.7.2 Sequential Experimentation with Resolution IV Designs

The 2^k factorial designs introduced in Chapter 6 can become very large as the number of factors increase. For example, when k = 6, 64 runs are required for the complete 2^k factorial design. These runs furnish the ability to calculate every interaction between the factors, up to the k factor interaction of ...
