Factorial Experiments in Cyclic Designs [PDF]

open access: bronzeThe Annals of Statistics, 1973
The use of cyclic incomplete block designs for factorial experiments is considered. Necessary and sufficient conditions are established under which a cyclic design for an $m \times n$ factorial experiment will give an orthogonal analysis of the main effects and interaction.

Rerandomization in $2^{K}$ factorial experiments [PDF]

open access: yesAnnals of Statistics, 2020
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 ...

Inference from Randomized (Factorial) Experiments [PDF]

open access: hybridStatistical Science, 2017
This is a contribution to the discussion of the interesting paper by Ding [Statist. Sci. 32 (2017) 331–345], which contrasts approaches attributed to Neyman and Fisher. I believe that Fisher’s usual assumption was unittreatment additivity, rather than the “sharp null hypothesis” attributed to him.

Comparison Between some Methods of Tackling the Lack of Experimental Units Needed for Application of Factorial Experiments [PDF]

open access: goldالمجلة العراقية للعلوم الاحصائية, 2011
Most of the time the researcher confronts a decrease in the experimental units required when applying a certain design, this problem appears especially when conducting the factorial experiments which mostly need great numbers of experimental units, to ...

Correlation of hardness of aluminum composites obtained by stir casting technology and the size and weight fraction of reinforcing Al2O3 particles [PDF]

open access: yesHemijska Industrija, 2021
In this work, the stir casting method was applied to obtain composites based on the alloy AN EW 6061 used as a metal base, and Al2O3 particles as a reinforcement. Composites play a significant role as engineering materials.

Advanced row-column designs for animal feed experiments

open access: yesIndian Journal of Animal Sciences, 2023
Inappropriate statistical designs may misinterpret results of animal feed experiments. Thus complete statistical designs can make animal feed research more appropriate and cost effective.

Concentration of cane-sugar syrup in a pilot scale climbing film evaporator [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2018
A climbing film evaporator is similar to a vertical tube heat exchanger, where a hot fluid, such as steam is introduced in shell side and a cold fluid such as sugar syrup is fed in tube side.
