Scientific Computing Research Environments for the Mathematical Sciences (SCREMS)

我们建议购买两个Dell PowerEdge 1955 Gig E高性能群集、IMSL F90和C数值库以及其他软件。该设备和软件将致力于支持各种项目的研究，包括神经元电生理数据的统计分析，贝叶斯结构方程建模与退伍军人健康管理局调查数据的应用，分层结构人群中遗传变异模式的统计分析，缺失值对推断的影响，以及高频金融数据的分析。 通过这些项目，我们旨在为统计方法和计算，复杂的统计建模，软件开发和数理统计做出贡献。 拟议的设备还将大大加强康涅狄格大学统计系各级的研究和教育基础设施。 由拟议的高性能设备支持的研究涵盖了从医学、遗传学、脑科学、金融到医疗保健的各个领域。 这些领域的发现对社会、经济、科学和技术产生了深远的影响。 然而，这些领域的研究人员越来越多地面临着分析大型复杂数据集的挑战。 拟议的设备将为我们提供应对挑战的宝贵能力，从而大大促进我们实现科学和技术突破的努力。

We propose to purchase two Dell PowerEdge 1955 Gig E High-Performance Clusters and IMSL F90 and C numerical libraries as well as other software. The equipment and software will be dedicated to the support of research in a variety of projects, including statistical analysis for neuronal electrophysiological data, Bayesian structural equations modeling with applications to Veterans Health Administration survey data, statistical analysis of patterns of genetic variation in hierarchically structured populations, the effect of missing values on inference, and analysis of high-frequency financial data. Through these projects, we aim to make contributions to statistical methodology and computing, complex statistical modeling, software development and mathematical statistics. The proposed equipment will also greatly enhance the research and education infrastructure of the Department of Statistics at University of Connecticut at all levels. The research supported by the proposed high-performance equipment covers areas spanning from medical science, genetics, brain science, finance to health care. Discoveries in these areas constantly have far reaching impact to society, economy, science and technology. However, researchers in these areas are increasingly facing challenges of analyzing large and complex datasets. The proposed equipment will provide us with invaluable capacity to address the challenges, hence significantly facilitating our efforts to make scientific and technological breakthroughs.
