How this book is organized?

By and large, I focus on concepts like mean, variance, covariance, notions of spread, distances, and their relationships with linear combinations, projections—that sort of thing. You will learn how to express statistical concepts with vector and matrix notation. The underlying goal is to show you how to get a geometrical interpretation of common statistical operations.
