報(bào)告摘要:

                In this talk, I will discuss the central limit theorem (CLT) for the linear spectral statistics (LSS) of sample correlation matrix, constructed from a pxn data matrix X with independent and identically distributed entries having mean zero, variance one, and infinite fourth moments in the high-dimensional regime n/p tending to c in (0,infinity)\ (1). Especially a necessary and sufficient condition for the CLT is presented.
