2k Factorial Design In R. General full factorial designs that contain factors with more than two levels. The Real Statistics Resource Pack contains the following array functions.
The number of runs necessary for a 2-level full factorial design is 2 k where k is the number of factors. 2-level full factorial designs that contain only 2-level factors. As the number of factors in a 2-level factorial design increases the number of runs necessary to do a full factorial design.
2k-1 one-half fraction 2k-2 one-quarter fraction 2k-3 one-eighth fraction 2k-p 1 2pfraction.
As the number of factors in a 2-level factorial design increases the number of runs necessary to do a full factorial design. Run experiments in all possible combinations. We restrict our discussion to completely randomized designs with fixed factors. High referred as or 1 and low referred as -or -1.
