Mathematical Sciences Computing Research Environments

爱荷华大学统计和精算学系将购买计算机工作站和网络服务器，以扩大其现有的应用和数理统计研究网络。该设备将用于几个研究项目，包括：(1)空间数据的一些相关性检验问题(2)非线性连续时间模型的最大似然估计(3)半参数模型的推断及其在删失数据分析中的应用(4)广义多变量分类反应模型的最大似然方法(5)统计分析和规划的图形用户界面。这些项目都涉及发展基本的统计方法，这种方法有可能立即应用于社会问题。此外，所有项目都涉及高度计算密集的方法，并需要处理大量数据的能力。有些还需要高分辨率和动态图形功能。

The Department of Statistics and Actuarial Science at the University of Iowa will purchase computer workstations and network servers to augment its existing network for research in applied and mathematical statistics. The equipment will be used for several research projects including: (1) Some Correlation Testing Problems for Spatial Data (2) Maximum Likelihood Estimation of Nonlinear Continuous-Time Models (3) Inference for Semiparametric Models with Applications to Analysis of Censored Data (4) Maximum-Likelihood Methods for a Generalized Class of Multivariate Categorical Response Models (5) Graphical User Interfaces for Statistical Analysis and Planning. These projects all involve the development of fundamental statistical methodology which has potential for immediate applications to the problems of society. Furthermore, all of the projects involve highly computationally intensive methods and require the ability to handle large amounts of data. Several also require high-resolution and dynamic graphics capabilities.
