Why Statistics Is Not Mathematics and Why We Should Care About
... Statistics is a science in my opinion, and it is no more a branch of mathematics than are physics, chemistry, and economics; for if its methods fail the test of experience – not the test of logic – they are discarded. - John Tukey, 1962 ...

Chapter 2 Weak Convergence
... As the name suggests, convergence in distribution (also known as convergence in law) has to do with convergence of the distribution functions (or “laws”) of random variables. Given a random variable X, the distribution function of X is the function F (x) = P (X ≤ x). ...

CHAPTER 4 Probability Concepts
... In stating Definition 4.1, we used the terms experiment and event in their intuitive sense. Basically, by an experiment, we mean an action whose outcome cannot be predicted with certainty. By an event, we mean some specified result that may or may not occur when an experiment is performed. For instanc ...
