Lectures 1 and 2: In these two courses we will review several classical results on asymptotic of eigenvalues of large-dimensional sample covariance matrix. These results include the strong convergence of the empirical spectral distribution and the CLT for linear spectral statistics. Then, we apply these theories to the inferences on population covariance matrix.
Lectures 3 and 4: In these two courses, we will introduce a kind of robust location and scatter estimators, that is, the sample spatial median and sample spatial-sign covariance matrix. Then, we talk about the asymptotic theories for its eigenvalues and related applications in statistics.
In-Person Event. Location Of Short Courses: University of Ottawa
Graduate students and young researchers.
After completing this short course, attendants should be familiar with a range of concepts and recent results in random matrix theory, including the empirical spectral distributions, limiting spectral distributions, linear spectral statistics, etc. Moreover, they should have acquired knowledge about theoretical results on the eigenvalue distributions of certain high-dimensional random matrix models, particularly, the widely studied sample covariance matrix and spatial-sign covariance matrix. Lastly, attendants should also have acquired conceptual and practical understanding of differences between classical multivariate analysis and modern high-dimensional statistics.
