While James Dyson's eponymous company, Dyson Ltd., based in Malmesbury, United Kingdom, is known to make high-quality vacuum cleaners, Dyson might have saved himself and his company a lot of time and money if he had been aware of the factorial design approach to experimentation. In fact, as discussed below, the statement of Dyson on cause and effect is incorrect. It is possible to learn what improves a system by changing more than one input variable at a time. Furthermore, this learning can be…

Classic Regression Metamodels and Their Designs
This chapter discusses the basics of low-order polynomial regression metamodels and their designs, and presents designs for estimating unbiased estimators of the first-order effects—even if there are two-factor interactions.

An improved framework is proposed, called STRONG-X, that enhances the efficiency and efficacy of STRONG to widen its applicability to more practical problems and includes a newly-developed experimental scheme that consists of construction of optimal simulation designs and an assignment strategy for random number streams to obtain computational gains.
Factorial analysis for modeling large-scale grid integration of renewable energy sources
As more renewable power sources, such as wind, solar, and ocean wave, are added to the grid, there has been an increasing impact on the ability of system operators to deal with the added variability

The article presents the method of determining the biological yield of roots and tops of sugar beet before the harvest, which is based on experimental data obtained directly in the field, depending on the specific conditions of beetroots.
A novel two stage algorithm for construction of RBF neural models based on A-optimality criterion
A new method is proposed which improves the compactness of the resultant RBF neural model, but also the accuracy of estimated model coefficients by effectively incorporating the A-optimality design criterion into a recently proposed two-stage subset selection, while the computational efficiency is still retained from the original two- stage selection method by introducing a residual matrix.
Effect of resistor tolerance on the performance of resistor network—An application of the statistical design of experiment
Resistors come with different tolerances, but they are generally not seriously considered in circuit simulation as only the exact resistances are used. In actual implementation of a resistor network,
