STATISTICS USING MIDAS: DATA ANALYSIS OVER THE INTERNET

SBIR项目将全面开发和实施多变量归纳数据分析系统(MIDAS)，通过互联网提供对145个主要健康和社会科学数据库的交互数据分析，这些数据库包含来自7个社会计量学国家数据实现(http://www.socio.com).)的150,000多个变量MIDAS将包括搜索和检索编程以及高度组织的可变级别和研究级别的链接，这些链接指向数千页的辅助文件，例如原始工具、码本、用户指南和方法报告。集成的Java脚本界面将允许用户通过支持Java的互联网浏览器快速、轻松且廉价地与系统交互。在线数据分析程序将包括加权和未加权的频率、百分位数、离散度和中心趋势的量度，以及带有关联度的双向和n向表、均值比较(两组和方差分析)和相关性，以及复方差估计的计算。用户将能够定义案例子集、重新编码、汇总以供分析，并生成可下载或打印的输出。自定义数据集下载也将可用。MIDAS将包括一个快速统计引擎、最先进的界面和“便携文档格式”文件，以确保数据分析速度和综合可用性。Midas将与许多Socionet功能集成，例如Verity搜索和安全商业交易。测试版将用于评估和改进所有功能。拟议的商业应用：多变量交互数据分析系统的商业可行性基于以下证据：[1]当前对社会计量学数据和工具档案产品的需求；[2)对在线数据分析的兴趣增加，[3)当前的竞争程度较低，以及[4]机构目标市场的规模，如面向健康和社会科学的学术部门、图书馆和研究机构，这些市场总计有数十万名研究人员、教师、学生、参考人员和其他对国家健康和社会科学统计资源的易于使用、定制的在线查询感兴趣的人。

The SBIR project will fully develop and implement a Multivariate Intractive Data Analysis System (MIDAS) to provide broad access to interactive data analysis, via the Internet, of 145 premier health and social science database containing over 150,000 variables from seven of Sociometrics' national data achieve (http://www.socio.com). MIDAS will include search and retrieval programming and highly organized variable-level and study-level links to several thousand pages of supporting documentation, e.g., original instruments, codebooks, User's Guides, and methodology reports. An integrated javascript interface will allow users to quickly, easily, and inexpensively interact with the system through Java-enabled Internet browsers. Online data analytic procedures will include weighted and unweighted frequencies, percentiles, and measures of dispersion and central tendency, as well as two-way and n-way tables with measures of association, comparison of means (2-group and ANOVA) and correlations, and the calculation of complex variance estimations. Users will be able to define case subsets, recodes, of aggregations for analysis, and them produce output which can be downloaded or printed. Custom dataset download will also be available. MIDAS will include a fast statistical engine, state-of-the-art interface, and "portable document format" files to ensure data analytic speed and comprehensive usability. MIDAS will be integrated with many Socionet features, e.g., Verity search and secure commercial transactions. Beta test panels will be used to assess and improve all features. PROPOSED COMMERCIAL APPLICATION: The commercial viability of the Multivariate Interactive Data Analysis System is based on evidence of: [1] current demand for Sociometrics' data and instrument archive products; [2] increased interest in online data analysis, [3] low levels of current competition, and [4] the size of institutional target markets, such as health and social science-oriented academic departments, libraries, and research organizations, which total several hundred thousand researchers, teachers, students, reference staff, and others interested in easy-to-use, customizable, online queries of national health and social science statistical resources.
