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 ...

Several new methodological issues that arise within two-way factorial designs for survival experiments are discussed within the framework of asymptotic theory for the proportional hazards model with ...

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 ...

Often you do not have the resources for a full factorial design. In this case, a fractional factorial design is a reasonable alternative, provided that the effects of interest can be estimated. Box, ...

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 ...
