In recent years, there has been increasing interest in the study of asymmetrical fractional factorial designs. Various new optimality criteria have been proposed from different principles for design ...

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 ...

This paper considers the construction of minimum aberration (MA) blocked factorial designs. Based on coding theory, the concept of minimum moment aberration due to Xu [Statist. Sinica 13 (2003) ...

Effect of Breast Magnetic Resonance Imaging on the Clinical Management of Women With Early-Stage Breast Carcinoma PURPOSE: Factorial designs may be proposed to test extra questions within a clinical ...

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 ...

ds is the name of the output data set for the constructed design. This data set contains variables for design factors and for a block factor, if the design uses blocking. Default names are used. The ...
