VOStat：面向天文学家的统计Web服务
VOStat: A Statistical Web Service for Astronomers
摘要：
VOStat是一个提供天文表格数据集交互式统计分析的Web服务。它通过SAMP通信系统被纳入与国际虚拟天文台有关的一套分析和可视化工具。用户向VOStat提供从VO中提取的数据集或以其他方式获取的数据集，并在$\sim 60$统计函数中进行选择。这些包括数据转换，绘图和汇总，密度估计，单样本和双样本假设检验，全局和局部回归，多变量分析和聚类，空间分析，方向统计，生存分析（用于上限等删失数据）和时间序列分析。使用公共领域{ \bf R}统计软件环境（包括其$>4000$ { \bf CRAN}附加包的一小部分）执行统计操作。VOStat的目的是促进比天文学中常用的更广泛的统计分析，并促进在{ \bf R}和{ \bf CRAN}中使用更先进的方法。
英文摘要：
VOStat is a Web service providing interactive statistical analysis of astronomical tabular datasets. It is integrated into the suite of analysis and visualization tools associated with the international Virtual Observatory (VO) through the SAMP communication system. A user supplies VOStat with a dataset extracted from the VO, or otherwise acquired, and chooses among $\sim 60$ statistical functions. These include data transformations, plots and summaries, density estimation, one- and two-sample hypothesis tests, global and local regressions, multivariate analysis and clustering, spatial analysis, directional statistics, survival analysis (for censored data like upper limits), and time series analysis. The statistical operations are performed using the public domain {\bf R} statistical software environment, including a small fraction of its $>4000$ {\bf CRAN} add-on packages. The purpose of VOStat is to facilitate a wider range of statistical analyses than are commonly used in astronomy, and to promote use of more advanced methodology in {\bf R} and {\bf CRAN}.
