Fractional factorial design

WIREs Computational Statistics, 2009
AbstractFractional factorial designs are among the most important statistical contributions to the efficient exploration of the effects of several controllable factors on a response of interest. Fractional factorials are widely used in experiments in fields as diverse as agriculture, industry, and medical research.

ON FRACTIONAL sm FACTORIAL DESIGNS

SUT Journal of Mathematics, 1999
Summary: The statistical structure of the fraction of symmetrical \(s^m\) factorial designs is investigated in some detail. In this paper, we show that the information matrix of a fractional \(s^m\) factorial design is determined completely by its characteristic vector.

Multistratum fractional factorial designs

Statistica Sinica, 2011
Summary: Recent work on multistratum fractional factorial designs is set in a general and unified framework, and a criterion for selecting multistratum fractional factorial designs that takes stratum variances into account is proposed. Application of the general theory is illustrated on designs of experiments with multiple processing stages, including ...

D‐optimal minimax fractional factorial designs

Canadian Journal of Statistics, 2013
AbstractThe D‐optimal minimax criterion is proposed to construct fractional factorial designs. The resulting designs are very efficient, and robust against misspecification of the effects in the linear model. The criterion was first proposed by Wilmut & Zhou (2011); their work is limited to two‐level factorial designs, however.

Fractional factorial designs for legal psychology

Behavioral Sciences & the Law, 2002
AbstractResearchers considering novel or exploratory psycholegal research are often able to easily generate a sizable list of independent variables (IVs) that might influence a measure of interest. Where the research question is novel and the literature is not developed, however, choosing from among a long list of potential variables those worthy of ...

Design-Plots for Factorial and Fractional-Factorial Designs

Journal of Quality Technology, 1998
This chapter develops design-plots for viewing the set of run conditions for experiment designs. The emphasis is on factorial and fractional factorial designs but mixture designs nested designs and irregular designs are also presented. The fundamental concept for designs with more than two factors is to place points on a regular grid.

Minimising drag coefficient of a hatchback car utilising fractional factorial design algorithm

European Journal of Computational Mechanics, 2018
Aerodynamic force is known as one of the most important attributes, which has significant weight on fuel consumption and vehicle performance. In this paper, minimising drag coefficient is performed considering modification of rear end factors.
