SOFTWARE FOR ANALYSING DATA FROM COMPLEX DENTAL SURVEYS

开发数据分析软件包（SUDAAN）， 适合于分析复杂的抽样调查是一个持续的 国家卫生统计中心的项目通过合同 三角研究所（RTI） SUDAAN是一个集合几个 采用最先进技术的高级统计程序 方法，泰勒级数或德尔塔估计方法，用于分析 数据来自复杂的抽样调查设计。 数据来自两个儿童，成人 和老年人牙科调查被用来分析测试， 从五个方面评估SUDAAN： .复杂调查样本的适当方法 .便携性 .可靠性/数值精度 .计算效率 .易于修改/增强 这些领域的工作正在进行，有中级（测试）主机 和SUDAAN的PC软件版本。

The development of a data analysis software package (SUDAAN) that is appropriate for the analysis of complex sample surveys is an ongoing project of the National Center for Health Statistics through a contract with Research Triangle Institute (RTI). SUDAAN is a collection of several high level statistical procedures that employ state-of-the-art methodology, Taylor series or Delta method of estimation for analyzing data from complex sample survey designs. Data from two Children's, Adults and Seniors Dental Surveys are being used to analytically test and evaluate SUDAAN in five areas: . appropriate methodology for complex survey samples . portability . reliability/numerical accuracy . computational efficiency . ease of modification/enhancement Work is proceeding in these areas with intermediate (testing) mainframe and PC software versions of SUDAAN.
