BIOSTATISTICS

生物统计核心将继续作为所有相关项目和核心的资源和合作者 到这个项目项目。生物统计核心人员负责监督数据采集， 执行数据输入和数据管理任务的所有软件，并培训 适当的人员。他们还负责与调查人员及其工作人员合作 监控数据采集过程，以确定潜在的问题来源并提出更改建议。 生物统计核心将在提案中概述的所有跨项目数据分析中发挥带头作用。 具体地说，生物统计核心将： 1.就所有项目的设计进行咨询，并就适当的统计和统计方法的应用进行咨询 方法论技巧。 2.协作所有核心和项目的数据分析和报告准备。 3.合作设计要使用的所有表格。 4.继续支持数据输入和数据管理程序，以实现成本效益高的计算机 使用。 5.便利所有调查员查阅核心收集的数据。 6.开发、应用和实施适当的统计数据分析技术，以结合 已收集的横截面和纵向数据。

The Biostatistics Core will continue to serve as a resource and collaborator for all projects and cores related to this program project. The Biostatistics Core personnel are responsible for overseeing data acquisition, for the implementation of all software for data entry and data management tasks, and for training the appropriate personnel. They are also responsible for collaborating with investigators and their staff in monitoring the data acquisition process to identify potential sources of problems and recommend changes. The Biostatistics Core will take a lead in all of the cross-project data analyses outlined in the proposals. Specifically the Biostatistics Core will: 1. Consult on the design of all projects and consult in the application of appropriate statistical and methodological techniques. 2. Collaborate in data analysis and report preparation for all cores and projects. 3. Collaborate in the design of all forms to be used. 4. Continue to support data entry and data management procedures to achieve cost-effective computer use. 5. Facilitate access by all investigators to data collected by the cores. 6. Develop, apply, and implement appropriate statistical data analysis techniques for combining the cross-sectional and longitudinal data that have been gathered.
