高维统计推断与随机矩阵

High Dimensional Statistical Inference and Random Matrices

Iain M. Johnstone

摘要:

多变量统计分析涉及对几个变量的观察,这些变量被认为具有某种程度的相互依赖性。在遗传学和社会科学问题的推动下,它在上个世纪上半叶首次开花。随后,随机矩阵理论(RMT)发展起来,最初在物理学中,最近在数学中广泛应用。虽然RMT的一些中心研究对象与多元统计学的研究对象相同,但统计理论在利用这种联系方面进展缓慢。然而,随着大量数据的收集越来越普遍,数据集现在通常具有与观察到的个体数量一样多或更多的变量。在这种情况下,RMT的技术和结果有很多提供多元统计。本文回顾了迄今为止取得的一些进展。

英文摘要:

Multivariate statistical analysis is concerned with observations on several variables which are thought to possess some degree of inter-dependence. Driven by problems in genetics and the social sciences, it first flowered in the earlier half of the last century. Subsequently, random matrix theory (RMT) developed, initially within physics, and more recently widely in mathematics. While some of the central objects of study in RMT are identical to those of multivariate statistics, statistical theory was slow to exploit the connection. However, with vast data collection ever more common, data sets now often have as many or more variables than the number of individuals observed. In such contexts, the techniques and results of RMT have much to offer multivariate statistics. The paper reviews some of the progress to date.
