Abstract

A procedure is given for treating boundary line overlap in computer simulated sampling. This procedure, referred to as algorithm EDGE, insures that each point in the rectangular population has the same probability of being included in the sample, thereby eliminating possible edge-effect bias. The effectiveness of EDGE in producing a more realistic variance/plot size relationship is demonstrated by comparing the variance functions with uncorrected samples and samples corrected using a previously reported weighting scheme.
