Nearest Neighbor Adjusted Best Linear Unbiased Prediction In Field Experiments, Walter W. Stroup

Conference on Applied Statistics in Agriculture

In field experiments with large numbers of treatments, inference can be affected by 1) local variation, and 2) method of analysis .

The standard approach to local, or spatial, variation in the design of experiments is blocking. While the randomized complete block design is obviously unsuitable for experiments with large numbers of treatments, incomplete block designs - even apparently well-chosen ones - may be only partial solutions. Various nearest neighbor adjustment procedures are an alternative approach to spatial variation .

Treatment effects are usually estimated using standard linear model methods. That is, linear unbiased estimates are obtained using ordinary least …
