Disease ratings were made in four plots on a total of 512 plants in eight square lattices of 64 plants each.

The program allows for rapid and concise analysis of the spatial pattern of binomial (presence/absence) data within a two-dimensional matrix (e.g., rows and columns of plants). The procedure is particularly useful for the detection and quantification of nonrandom spatial patterns, average cluster size, distance between or among clusters, relative cluster location within a lattice, within-row and across-row aggregation, and edge effects (.)}, number={4}, journal={PLANT DISEASE}, author={NELSON, SC and MARSH, PL and CAMPBELL, CL}, year={1992}, month={Apr}, pages={427–432} }
