The spatial scan statistic is commonly used for geographical disease cluster detection, cluster evaluation and disease surveillance. The most commonly used shape of the scanning window is circular. In this paper we explore an elliptic version of the spatial scan statistic, using a scanning window of variable location, shape (eccentricity), angle and size, and with and without an eccentricity penalty. The method is applied to breast cancer mortality data from Northeastern United States and female oral cancer mortality in the United States. Power comparisons are made with the circular scan statistic.
空间扫描统计量通常用于地理疾病聚集性检测、聚集性评估和疾病监测。扫描窗口最常用的形状是圆形。在本文中，我们探索了空间扫描统计量的椭圆版本，使用位置、形状（偏心率）、角度和大小可变的扫描窗口，并且考虑有无偏心率惩罚。该方法应用于美国东北部的乳腺癌死亡率数据和美国女性口腔癌死亡率数据。并与圆形扫描统计量进行了功效比较。
