On the Creation of Acceptable Conjoint Analysis Experimental Designs
针对联合分析中正交分数因子设计可能产生不具代表性刺激组合的问题，提出一种基于组合优化的新方法，生成尽可能正交且不含非代表性刺激的设计。
ABSTRACT Conjoint analysis studies typically utilize orthogonal fractional factorial experimental designs to construct a set of hypothetical stimuli. Occasionally, these designs include environmentally correlated attributes that can lead to stimulus profiles that are not representative of the subject's environment. To date, no one has proposed a remedy well‐grounded in statistical theory. This note presents a new methodology utilizing combinatorial optimization procedures for creating modified fractional factorial designs that are as “orthogonal” as possible, which do not contain nonrepresentative stimulus profiles.
