Table 4 Comparison of the circular and the flexible spatial scan statistic for the cluster model C. Comparison of bivariate power distribution P(l, s) × 1000 between the circular spatial scan statistic and the flexible spatial scan statistic for the hot-spot cluster C = {14, 15, 26, 27}. Nominal α-level is set as 0.05 and 1000 trials are carried out. For more details, see text.
