SaTScan: Spatial Scan Statistic Surveillance Software

SaTScan是一个免费的软件产品，用于地理集群检测和推理。它用于评估诸如疾病发病率或死亡率等观察结果是否在空间和/或时间上随机分布，或者是否存在比预期病例更多（或更少）的具有统计意义的空间和/或时间群集。它已被广泛用于慢性疾病，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暴发。随着用户数量的增加，有不同类型的数据和不同类型的问题需要回答，对新的SaTScan特性和功能的需求没有得到满足，包括开发不同类型数据的基础统计方法的新变体，更广泛的输入和输出选项，增强用户友好性，提高大型数据集的速度，替代操作系统的版本，以及更广泛、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.
