背景：Kulldorff提出的空间扫描统计量已被广泛应用于各种流行病学研究中的聚集性检测。然而，该扫描统计使用圆形窗口来定义潜在的簇区域，因此难以正确地检测实际的非圆形簇。Duczmal和Assenção最近提出的一项探测非圆形星团的建议显示，他们探测到的是一个形状非常不规则的星团，它比我们经验中的真实星团要大得多。
Background: The spatial scan statistic proposed by Kulldorff has been applied to a wide variety of epidemiological studies for cluster detection. This scan statistic, however, uses a circular window to define the potential cluster areas and thus has difficulty in correctly detecting actual noncircular clusters. A recent proposal by Duczmal and Assunção for detecting noncircular clusters is shown to detect a cluster of very irregular shape that is much larger than the true cluster in our experiences.
