Title: Statistical Problems of Big Data with some Applications in Finance
Abstract: Big data is ubiquitous and often exhibits phenomena transcending the boundary of classical multivariate statistical analysis. We shall illustrate some limitations of classical statistical techniques in regression and multivariate analysis problems when the dimension of the data is large and present some recent developments on addressing these issues using the theory of random matrices. We shall then present a financial application of portfolio selection from a huge number of available assets using methods of Bayesian multiple testing.
