An Evaluation of Error Variance Bias in Spatial Designs

摘要

AbstractSpatial design and analysis are widely used, particularly in field experimentation. However, it is often the case that spatial analysis does not significantly enhance more traditional approaches such as row–column analysis. It is then of interest to gauge the degree of error variance bias that accrues when a spatially designed experiment is analysed as a row–column design. This paper uses uniformity data to study error variance bias in$$7imes 12$$7×12spatial designs for 21 treatments.]]>
