We can run a fraction of a full factorial experiment and still be able to estimate main effects: Consider the two-level, full factorial design for three factors ...
Design of experiments > Factorial designs > Full Factorial ... Clearly if the number of factors is large, typically greater than 5 or 6, or if more than two factor levels are included, the number of runs required becomes unmanageable (especially if replication is also included) so consideration must be given to only running a subset or fraction of the full factorial design. Chapter 6: Fractional factorial designs - Chalmers Fractional factorial designs • A design with factors at two levels. • How to build: Start with full factorial design, and then introduce new factors by ... https://www.itl.nist.gov/div898/handbook/pri/section3/pri3342.htm https://www.itl.nist.gov/div898/handbook/pri/section3/pri3341.htm
PDF FACTORIAL DESIGNS Two Factor Factorial Designs balanced two-factor factorial design. A balanced a bfactorial design is a factorial design for which there are alevels of factor A, blevels of factor B, and nindependent replications taken at each of the a btreatment combinations. 9.1 - 3^k Designs in 3^p Blocks | STAT 503 These designs are not used for screening as the 2 k designs were; rather with three levels we begin to think about response surface models. Also, 3 k designs become very large as k gets large. With just four factors a complete factorial is already 81 observations, i.e. N = 3 4 .

Design of Experiments – Full Factorial Designs |… In designs where there are multiple factors, all with a discrete group of level settings, the full enumeration of all combinations of factor levels is referred toTo create the full factorial design for an experiment with three factors with 3, 2, and 3 levels respectively the following code would be used 5.9. Fractional factorial designs — Process Improvement… The remaining 10 three-factor interactions, 5 four-factor interactions, a single five- factor interaction are likely not too important either, at least initially. A full factorial would estimate 32 effects, even if we likely only interested in at most 16 of them (5 main effects + 10 of the 2fi’s + 1 intercept).
