Construction of 2fi-optimal row-column designs [PDF]
arXiv, 2023 Row-column factorial designs that provide unconfounded estimation of all main effects and the maximum number of two-factor interactions (2fi's) are called 2fi-optimal. This issue has been paid great attention recently for its wide application in industrial or physical experiments.

Reparametrisation of interest in non-uniform factorial designs [PDF]
, 2000 A definition of factorial effects relying on the treatment structure defined by the hierarchies is proposed. It applies to a non-uniform situation, where the number of levels of a nested factor within the classes defined by each set of levels of its ...

On Randomization-based and Regression-based Inferences for 2^K Factorial Designs [PDF]
arXiv, 2016 We extend the randomization-based causal inference framework in Dasgupta et al. (2015) for general 2^K factorial designs, and demonstrate the equivalence between regression-based and randomization-based inferences. Consequently, we justify the use of regression-based methods in 2^K factorial designs from a finite-population perspective.

Rerandomization in $2^K$ Factorial Experiments [PDF]
arXiv, 2018 With many pretreatment covariates and treatment factors, the classical factorial experiment often fails to balance covariates across multiple factorial effects simultaneously. Therefore, it is intuitive to restrict the randomization of the treatment factors to satisfy certain covariate balance criteria, possibly conforming to the tiers of factorial ...

Improving Covariate Balance in 2^K Factorial Designs via Rerandomization [PDF]
arXiv, 2015 Factorial designs are widely used in agriculture, engineering, and the social sciences to study the causal effects of several factors simultaneously on a response. The objective of such a design is to estimate all factorial effects of interest, which typically include main effects and interactions among factors.

Identification of Dispersion Effects in 2k Factorial Design
Brazilian Journal of Operations & Production Management, 2010 The identification of dispersion effects is a very important stage in developing robust products and processes. Several methods to identify dispersion effects are present in statistical and quality engineering literature, especially methods which use 2K ...
