Abstract

In this article, I provide a detailed discussion of the well-known fish patty experiment introduced in the literature by the late John A. Cornell in the first edition of his famous textbook on the design and analysis of mixture experiments. Cornell used the fish patty experiment as the motivating example for an article discussing that, for logistical reasons, many mixture-process variable experiments are run using a split-plot experimental design. More specifically, he described two possible ways in which the fish patty experiment might have been performed, both of which require a split-plot analysis of the data. These descriptions were not followed by the corresponding analyses of the fish patty data. Moreover, Cornell did not discuss the most convenient way in which the fish patty experiment could have been run, namely using a strip-plot design. In this article, I discuss the logistics leading to a strip-plot design, conduct the corresponding strip-plot analysis and contrast it with the two split-plot analyses.

摘要

在这篇文章中，我将详细讨论已故的约翰·A·康奈尔在他著名的混合实验设计和分析教科书第一版中介绍的著名的鱼肉饼实验。康奈尔大学使用鱼肉饼实验作为一篇文章的激励示例，该文章讨论了出于逻辑原因，许多混合过程变量实验是使用裂区实验设计进行的。更具体地说，他描述了可能进行鱼饼实验的两种可能方式，这两种方式都需要对数据进行裂区分析。这些描述之后没有对鱼肉饼数据进行相应的分析。此外，康奈尔没有讨论进行鱼饼实验的最方便的方法，即使用条形图设计。
