The use of the scan statistic in testing for clustering in time is discussed with particular reference to a reported clustering of trisomies in spontaneous abortions in New York City. The scan statistic is the maximum number of observed cases in an interval of preselected length, as the interval is allowed to scan, or slide along, the time frame of interest. A table of the lower tail of the distribution of this statistic is given.
本文讨论了扫描统计量在时间聚类检验中的应用，特别参考了纽约市自然流产中三体性聚类的报告。扫描统计量是在预先选定长度的区间内观察到的最大病例数，该区间可以在感兴趣的时间范围内扫描或滑动。给出了该统计量分布下尾的表格。
