Because relatively fewer cells are coastal as the block size increases, the frequency array becomes more clustered as proportionately more points appear in single cells. Consequently, the scale with the highest redundancy will be the optimum block size for the identification of major clusters of ship-building firms. A. Theoretical and Statistical Anscombe, F.J.
