报告题目: Matrix rank/inertia methodology and its applications in statistics
报告摘要: Thousands of analytical formulas for calculating rank and inertias of (square) matrices were established in past several decades by many authors. These formulas are easy to understand in mathematics and easy to use in applications, and now become a series of simple, explicit, and useful analysis methodology in mathematical science and other disciplines. In this talk, I introduce how to establish expansion formulas for calculating rank/inertias of matrices, how to prove equalities and inequalities via matrix rank/inertia formulas, and how to derive exact solutions of some matrix-valued function optimization problems in the Löwner partial ordering. I also introduce some applications of the matrix rank/inertia methodology in statistical analysis and inference of linear regression models.
