Data And Methods Core

项目总结/摘要 数据和方法核心将提供数据管理和分析方法方面的跨领域专业知识。的 核心包括在该计划所涉及的数据和方法方面具有丰富经验的研究人员 项目它将在所有项目的共同问题上发挥领导作用， 复杂的数据集和分析，以及推进计划项目科学目标的新方法。 核心有三个主要目标。首先，核心将协调数据资源，包括获取，准备， 整合、管理和确保项目所需数据的质量。在项目中，许多数据 挑战可以在核心中一次解决，而不是在每个项目中单独解决， 解决数据问题的方法和计划项目资源的成本效益。第二，核心将提供 对项目分析问题的一般分析专业知识，如测量开发，建模技术， 经济理论、因果推理和统计推理。在项目范围内应用专业知识 将使调查人员能够查明贯穿各领域的问题，并制定可广泛适用的解决办法。 第三，核心将开发和应用与缺失数据和准实验设计相关的新方法。 方法学工作将与项目的研究需求紧密结合，使项目的研究更加有力， 严谨的研究结论。 医疗保险计划对老年人的健康、福利和经济安全至关重要，对联邦政府也至关重要。 政府的预算。该计划项目在数据与方法核心的领导和支持下，将 使用具有广泛代表性的数据进行实证分析，仔细指定临床质量的衡量标准， 资源使用和严格的统计方法。

PROJECT SUMMARY/ABSTRACT The Data & Methods Core will provide cross-cutting expertise in data management and analysis methods. The Core comprises researchers with extensive experience with the data and methods involved in the Program Project. It will provide leadership on issues common to all projects, day-to-day direction in the management of complex data sets and analyses, and novel methods to advance the scientific goals of the Program Project. The Core has three primary aims. First, the Core will coordinate data resources, including acquiring, preparing, integrating, managing, and ensuring quality of the data needed for projects. Across projects, many data challenges can be solved once in the core rather than individually in each project, ensuring uniformity in approach to data issues and cost-effective use of Program Project resources. Second, the Core will provide general analytical expertise on Project analysis issues such as measure development, modeling techniques, economic theory, causal inference, and statistical inference. Applying expertise across the range of projects will enable investigators to identify cross-cutting issues and develop solutions that can be broadly applied. Third, the Core will develop and apply novel methods relevant to missing data and quasi-experimental designs. The methodological work will closely align with the research needs of the projects, enabling more robust and rigorous research conclusions. The Medicare program is vital to the health, welfare, and financial security of older adults and to the federal government's budget. This Program Project, with leadership and support from the Data & Methods Core, will conduct empirical analysis with broadly representative data, carefully specified measures of clinical quality and resource use, and rigorous statistical methods.
