The projects proposed in this grant study diverse populations, but have a common set of goals and research hypotheses. In addition, they each utilize similar study designs-2-armed randomized clinical trial-and share, in the main, a common set of variables to be measured to achieve these goals. A common set of analytic problems are faced by this grant- innovative statistical methods for the study of longitudinal data can be applied to the data sets, complex analyses of the psychometric properties of the measures to be utilized will be necessary, and the data lend themselves to causal and multivariate modeling. From an analysis point of view, the similarity of analytic problems faced by the researchers because of design and variables make a centralized facility with common personnel and equipment beneficial - the lessons learned in one project can be carried over to others, differences and commonalities across projects can be compared easily, and duplication of efforts is minimized. In addition, a centralized analysis core allows for a level of equipment and personnel not available to individual researchers and projects. The purpose of this core is to provide equipment, personnel and statistical expertise to address the analytic problems contained in this body of research. Several levels of assistance are to be provided - assistance with data entry and data management, provision of hardware and software for analysis, routine and complex statistical analysis of the resulting data, and advancement of statistical/methodological knowledge in the study of the effects of axial dysmobility. To achieve these goals, the hardware/software of the Center for Aging Computer and Statistics Lab with be coupled with a health economist and statistician who will direct the activities of a data entry person, a systems analyst, and a research analyst.

这项赠款研究中提出的项目各种各样的人群，但 共同的目标和研究假设。此外，他们每个 利用类似的研究设计2臂的随机临床试验和 共享一组通用的变量，要衡量以实现 这些目标。这项赠款面临的一组共同的分析问题 - 用于研究纵向数据的创新统计方法可以是 应用于数据集，心理测量的复杂分析 必须使用要使用的措施的特性，并且 数据将自己用于因果和多元建模。从一个 分析的观点，分析问题的相似性 由于设计和变量，研究人员成为集中式设施 有了普通人员和设备有益 - 在 一个项目可以转移给其他项目，差异和共同点 可以轻松比较整个项目，并重复努力 最小化。此外，集中分析核心允许一个水平 个别研究人员和不可用的设备和人员 项目。 该核心的目的是提供设备，人员和 统计专业知识以解决此中包含的分析问题 研究机构。提供几个级别的帮助 - 协助数据输入和数据管理，提供硬件 以及用于分析，常规和复杂统计分析的软件 由此产生的数据以及统计/方法论的进步 研究轴向障碍性影响的知识。实现 这些目标，老化计算机中心的硬件/软件， 统计实验室与健康经济学家和统计学家相结合 谁将指导数据输入人员的活动，系统 分析师和研究分析师。
