SaTScan: Spatial Scan Statistic Surveillance Software

SaTScan是一款免费的地理集群检测和推理软件产品。它用于评估疾病发病率或死亡率等观测数据是否在空间和/或时间上随机分布，或者是否存在具有统计意义的空间和/或时间集群，其病例比预期多(或少)。它已被广泛用于慢性病，如评估癌症聚集性是否可能是由于偶然，以及用于传染病，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，需要回答不同类型的数据和不同类型的问题，对新的SATScan特性和功能的需求尚未得到满足，其中包括开发新的SATScan特性和功能、针对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、针对替代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，以满足其中许多需求。

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.
