Mixed-strain housing for female C57BL/6, DBA/2, and BALB/c mice: validating a split-plot design that promotes refinement and reduction [PDF]

open access: yesBMC Medical Research Methodology, 2016
Background Inefficient experimental designs are common in animal-based biomedical research, wasting resources and potentially leading to unreplicable results. Here we illustrate the intrinsic statistical power of split-plot designs, wherein three or more

Construction of Optimal Split-Plot Designs for Various Design Scenarios

open access: yesFractal and Fractional, 2022
When performing fractional factorial experiments in a completely random order is impractical, fractional factorial split-plot designs are suitable options as an alternative. It is well recognized that the more there are lower order effects of interest at

Minimum Aberration Split-Plot Designs Focusing on the Whole Plot Factors

open access: yesMathematics, 2022
In some experiments, the levels of some factors are difficult to change; then fractional factorial split-plot (FFSP) designs are suitable for selection.

Nonlinear split-plot design modeling and analysis of rice varieties yield

open access: yesScientific African, 2023
In this research, a class of nonlinear split plot design models where the mean function of the split-plot model is not linearizable is presented. This was done by fitting intrinsically nonlinear split-plot design (INSPD) models using the Chapman-Richards

Optimal Split-Plot Designs [PDF]

open access: yesJournal of Quality Technology, 2002
Split-plot designs are heavily used in industry, especially when factor levels are difficult or costly to change or to control. This is because this type of design avoids too many changes of the whole plot factor levels, which leads to considerable savings in cost and time. The purpose of this chapter on split-plot designs is twofold.

Study of the Effect of Potato Lifter Line on Some Properties at Different Depths and Varieties of Potato Crop

open access: yesActa Technologica Agriculturae, 2023
This research aims to study the effect of the number of harvest rows under two digging depths and cultivars on the quality of harvesting potatoes (damage and losses). The experiment was factorial, using a randomised complete block design with split-split

D-OPTIMAL DESIGNS FOR SPLIT-PLOT MIXTURE PROCESS VARIABLE DESIGNS OF THE STEEL SLAG EXPERIMENT

open access: yesBarekeng, 2022
The nature of the steel slag concrete experiment followed a mixture process variable (MPV) design. In this study, the concrete is composed of five mixture components, cement, fine aggregate, coarse aggregate, percentage steel slag replaced the fine ...

Conseqüências da análise incorreta de experimentos blocados The consequences of incorrect analysis of blocked experiments

open access: yesQuímica Nova, 2007
Errors are always present in experimental measurements so, it is important to identify them and understand how they affect the results of experiments. Statistics suggest that the execution of experiments should follow random order, but unfortunately the ...
