Correcting for spatial heterogeneity in plant breeding experiments with P-splines
An important aim of the analysis of agricultural field experiments is to obtain good predictions for genotypic performance, by correcting for spatial effects. In practice these corrections turn out to be complicated, since ...
Modelling spatial trends in sorghum breeding field trials using a two-dimensional P-spline mixed model
Adjustment for spatial trends in plant breeding field trials is essential for efficient evaluation and selection of genotypes. Current mixed model methods of spatial analysis are based on a multi-step modelling process ...
