2k-p fractional factorial designs vs Plackett-Burman designs (similarities and differences)
Regarding the 2k-p fractional factorial designs (n= 4, 8, 16, 32, etc) & Plackett-Burman designs that are not a power of 2 (eg, n= 12, 20, 24, etc).a. What is similar about these two types of designs especially regarding their balance and orthogonality properties?b. What is the main difference between these two types of designs especially regarding 2 factor interactions? I know the following:2k-p ...
