Step-up simultaneous tests for identifying active effects in orthogonal saturated designs [PDF]

open access: yesAnnals of Statistics 2007, Vol. 35, No. 1, 449-463, 2007
A sequence of null hypotheses regarding the number of negligible effects (zero effects) in orthogonal saturated designs is formulated. Two step-up simultaneous testing procedures are proposed to identify active effects (nonzero effects) under the ...

Blocked regular fractional factorial designs with minimum aberration [PDF]

open access: yesAnnals of Statistics 2006, Vol. 34, No. 5, 2534-2553, 2005
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.

Regression tree models for designed experiments [PDF]

open access: yesIMS Lecture Notes--Monograph Series 2006, Vol. 49, 210-228, 2006
Although regression trees were originally designed for large datasets, they can profitably be used on small datasets as well, including those from replicated or unreplicated complete factorial experiments.

A trigonometric approach to quaternary code designs with application to one-eighth and one-sixteenth fractions [PDF]

open access: yes, 2011
The study of good nonregular fractional factorial designs has received significant attention over the last two decades. Recent research indicates that designs constructed from quaternary codes (QC) are very promising in this regard.

Generalized resolution for orthogonal arrays [PDF]

open access: yes, 2014
The generalized word length pattern of an orthogonal array allows a ranking of orthogonal arrays in terms of the generalized minimum aberration criterion (Xu and Wu [Ann. Statist. 29 (2001) 1066-1077]).

Independence Distribution Preserving Covariance Structures for the Multivariate Linear Model [PDF]

open access: yes, 1999
Consider the multivariate linear model for the random matrixYn×p∼MN(XB,V⊗Σ), whereBis the parameter matrix,Xis a model matrix, not necessarily of full rank, andV⊗Σ is annp×nppositive-definite dispersion matrix.

Generalized wordlength patterns and strength

open access: yes, 2012
Xu and Wu (2001) defined the \emph{generalized wordlength pattern} $(A_1, ..., A_k)$ of an arbitrary fractional factorial design (or orthogonal array) on $k$ factors.

Invariance of generalized wordlength patterns

open access: yes, 2008
The generalized wordlength pattern (GWLP) introduced by Xu and Wu (2001) for an arbitrary fractional factorial design allows one to extend the use of the minimum aberration criterion to such designs. Ai and Zhang (2004) defined the $J$-characteristics of

Uniform fractional factorial designs

open access: yes, 2012
The minimum aberration criterion has been frequently used in the selection of fractional factorial designs with nominal factors. For designs with quantitative factors, however, level permutation of factors could alter their geometrical structures and ...
