The previous example illustrates a complete factorial experiment involving eight runs and three factors: cutting speed (SPEED), feed rate (FEED), and tool angle (ANGLE). Now, suppose two machines (A ...

The Plackett-Burman design method is one of the most useful tools when you don’t have all the data available for an ...

Experimentation is a vital part of the scientific method. Most problems in science require observation of the system at work and experimentation to elucidate information about how the system works. In ...

The analysis of complex factorial experiments is performed most efficiently and reliably by means of a tabular procedure suggested by Yates and described originally for the case of n factors each at ...

This example uses statements for the analysis of a randomized block with two treatment factors occuring in a factorial structure. The data, from Neter, Wasserman, and Kutner (1990, p. 941), are from ...

How can the fractional factorial design of experiments benefit you? A global beverage company faced a persistent issue in its production line: excessive foaming while bottling 1-liter apple juice ...

The classical design (factorial design, response surface design, etc.) may fail to meet our requirements due to an irregular design space, involving categorical variables, a nonstandard model, or ...

In many experimental situations, a large portion of mean squares (including the higher-order interactions) may contain real effects. This paper introduces chain pooling, a procedure that tests for ...
