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

Split-Plot Central Composite Designs Robust to a Pair of Missing Observations

open access: yesJournal of Applied Sciences and Environmental Management, 2018
This study constructs robust split-plot central composite designs against missing pairs of observations. Split-plot central composite designs (CCD) consist of factorial (f), whole-plot axial (α), subplot axial (β), and center (c) points. A loss function

Missing Observations in Split-Plot Central Composite Designs: The Loss in Relative A-, G-, and V- Efficiency

open access: yesJournal of Applied Sciences and Environmental Management, 2021
The trace (A), maximum average prediction variance (G), and integrated average prediction variance (V) criteria are experimental design evaluation criteria, which are based on precision of estimates of parameters and responses. Central Composite Designs(

Aligned Rank Tests for Interactions in Split-Plot Designs: Distributional Assumptions and Stochastic Heterogeneity [PDF]

open access: yes, 2009
Three aligned rank methods for transforming data from multiple group repeated measures (split-plot) designs are reviewed. Univariate and multivariate statistics for testing the interaction in split-plot designs are elaborated.

Improvements in the processing of agricultural commodities: The case of cocoa liquor

open access: yesDyna, 2017
The solidification of the cocoa liquor is one of the most important steps for processing cocoa cultivars. This process is typically characterized as a continuous process, which may become a barrier for the randomization of the applied data treatments ...

Soil amendment with biochar and manure alters wood stake decomposition and fungal community composition

open access: yesGCB Bioenergy, 2023
Biochar and manure can be used for sustainable land management. However, little is known about how soil amendments might affect surface and belowground microbial processes and subsequent wood decomposition.
