无法考察交互作用的三因素设计(二)(英文)

Three-factor designs unable to examine the interactions (Part 2)

无法考察交互作用的三因素设计包括交叉设计和拉丁方设计两种。这两种设计类型较为特殊,所考察的三个因素包括一个实验因素和两个区组因素。尽管这两种设计在实际研究中运用的频率不是很高,但若在合适的场合正确运用这两种设计类型,将取得很好的实验效果。本文结合实例,介绍3×3交叉设计和拉丁方设计。

Three-factor designs that are unable to examine the interactions include crossover design and Latin square design, which can examine three factors, an experimental factor and two block factors. Although the two design types are not quite frequently used in practical research, an unexpected research effect will be achieved if they are correctly adopted on appropriate occasions. This article introduced the 3 × 3 crossover design and the Latin square design by examples.
