SaTScan: Spatial Scan Statistic Surveillance Software

SaTScan是一个用于地理聚类检测和推断的免费软件产品。它用于评估疾病发生率或死亡率等观察结果是否在空间和/或时间上随机分布，或者是否存在统计学显著的空间和/或时间集群，其中病例数比预期的多（或少）。它已被广泛用于慢性病，例如评估癌症集群是否可能是偶然的，以及传染病，例如每天监测急诊室数据以早期发现疾病爆发。随着用户数量的增加，需要回答的数据类型和问题类型各不相同，对新的SaTScan特征和功能的需求仍未得到满足，包括为不同类型的数据开发新的基本统计方法变体，增加输入和输出选项，增强用户友好性，提高大型数据集的速度，其他操作系统的版本，以及更广泛和更详细的文档。在这个项目中，我们建议进一步开发和维护SaTScan软件，以满足这些需求。

SaTScan is a free software product for geographical cluster detection and inference. It is used to evaluate whether observations such as disease incidence or mortality are randomly distributed over space and/or time, or whether there are statistically significant spatial and/or temporal clusters with more (or fewer) cases than expected. It has become widely used for chronic diseases, such as evaluating whether a cancer cluster is likely to be due to chance or not, as well as for infectious diseases, such as the daily monitoring of emergency room data for the early detection of disease outbreaks. As the number of users increase, with different types of data and different types of questions to be answered, there is an unmet need for new SaTScan features and functionalities, including the development new variations of the underlying statistical methods for different types of data, a wider variety of input and output options, enhancements to increase user-friendliness, increased speed for large data sets, versions for alternative operating systems, and broader and more detailed documentation. In this project, we propose to further develop and maintain the SaTScan software to fulfill many of these needs.
