Selection Of Blocked Two-Level Fractional Factorial Designs For Agricultural Experiments, Weiming Ke, Cuirong Ren, Huitian Lu

Conference on Applied Statistics in Agriculture

Blocked two-level fractional factorial designs are a very useful tool for efficient data collection in agricultural and other scientific research. In most experiments, in addition to the main effects, some two-factor interactions are also meaningful and need to be estimated. We propose a method for efficiently selecting blocked two-level fractional factorial designs when some of the two-factor interactions are non-negligible. We then present some results for a design with only 8 or 16 runs to illustrate how to use this method.
