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

Optimal Split-Plot Designs [PDF]

open access: yes, 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.

Estimation of Optimum Plot Size in Split-Split Plot Design Used in Field Experiment [PDF]

open access: yesThe Egyptian Statistical Journal, 1999
Estimates of soil heterogeneity are obtained from Split-Split plot design. A weighted regression analysis method is used to determine the soil heterogeneity from the analysis of variance technique of the above design.

Characterization and split-split-plot analysis of steamed factors affecting the swimming crab (Portunus trituberculatus) flavor quality

open access: yesFood Chemistry Advances, 2023
Swimming crab (Portunus trituberculatus) is a kind of popular crab for being rich in nutrition and intense in flavor. The time and heat exposure cause differences in flavor during steaming, dramatically affecting first impression and acceptability.

Testing Sub-hypotheses in Whole Plot Covariates in Non-Replicated Two-Way Split Plot Experiments [PDF]

open access: yesThe Egyptian Statistical Journal, 2000
The problem of analyzing a whole plot covariate in non-replicated two-way split plot experiments is considered. A test procedure is given that will enable the data analyst to determine subareas of the data in which the data are additive. The procedure is
