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

open access: goldScientific 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
