高维均值向量和协方差矩阵的齐性检验
本研究旨在开发高维均值向量和协方差矩阵的同质性检验,其中特征数可能大于样本量。我们引入两种分类加权统计来检验均值和协方差矩阵的相等性。我们建立了所提出的检验统计量在一定温和条件下的渐近分布,并开发了简化算法以方便实现和应用。仿真研究表明,在经验尺度和功率方面,所提出的测试具有令人满意的性能。我们还将提出的测试程序应用于两个微阵列数据集。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
