报告摘要：Sample correlation matrix plays an important role in multivariate statistical analysis, for example, in factor analysis, principal component analysis and etc. We study the limiting spectral distribution and central limit theorem (CLT) of linear spectral statistics of high-dimensional sample correlation matrix under the linear component structure and elliptical structure when the data dimension and sample size tend to infinity proportionally. The CLTs are used for high-dimensional testing problems of correlation matrix.
