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

Scientific 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

Journal 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
