Abstract

The article reports an analysis of a series of uniformity field trials using the technique recommended by a certain Gilmour, Cullis and Verbyla. It describes the role of the sample variogram and presents a range of enhanced graphical diagnostics to aid the spatial modeling process. It highlights the implications of the presence of extraneous variation related to commonly used agronomic practices.
