Data And Methods Core

项目摘要/摘要 数据与方法核心将提供数据管理和分析方法方面的交叉专业知识。这个 CORE由对该计划所涉及的数据和方法具有丰富经验的研究人员组成 项目。它将在所有项目的共同问题上提供领导，在管理方面提供日常指导 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。跨项目、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，确保 数据问题的解决方法和计划项目资源的成本效益使用。第二，核心将提供 在项目分析问题上的一般分析专长，如度量开发、建模技术、 经济理论、因果推理和统计推理。将专业知识应用于各种项目 将使调查人员能够确定贯穿各领域的问题并制定可广泛应用的解决办法。 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。 方法学工作将密切配合项目的研究需要，使之能够更有力和 严谨的研究结论。 医疗保险计划对老年人和联邦政府的健康、福利和经济保障至关重要 政府的预算。该计划项目在数据和方法核心的领导和支持下，将 使用具有广泛代表性的数据、仔细指定的临床质量衡量标准和 资源利用，以及严格的统计方法。

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.
