Table 5 Comparison of the circular and the flexible spatial scan statistic for the cluster model D. 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 D = {73, 74, 75, 76, 78}. Nominal α-level is set as 0.05 and 1000 trials are carried out. For more details, see text.
