Linear Algebra in Action

If you were an economist looking at a huge chunk of data regarding the market share of a product from three different companies, what would you make out of it? If you were a policymaker, how would you decide on the factors that affect the level of education in your country? If you were a manager at a betting company, how would you determine the odds of the college football playoffs? If I were in your shoes, I would use nothing but linear algebra. In this talk, I will introduce the concept of linear regression with a geometric approach, and then apply it to several real-life scenarios.
