1 Chebyshev’s Inequality Markov’s Inequality Proposition 2.1.

2 Chebyshev’s Inequality Chebyshev’s Inequality: Proposition 2.2. Consider Example 2a

3 Convergence in probability A sequence of random variables, X 1, X 2, …, converges in probability to a random variable X if, for every  > 0, or equivalently,

4 The weak law of large numbers Theorem 2.1. The weak law of large numbers Proof:

5 Almost Sure Convergence

6 The Strong Law of Large Numbers Theorem 4.1, p. 400

7 Convergence in distribution A sequence of random variables, X 1, X 2, …, converges in distribution to a random variable X if at all points x where F X (x) is continuous. This really says that the CDFs converge

8 Central Limit Theorem Theorem 3.1. For iid random variables X i Consider Examples 3b and 3c, p. 396

9 Central limit theorem for independent random variables Theorem 3.2, p. 399. (a)The is uniformly bounded, meaning for some M, (b) and

10 Jensen’s ineqality Proposition 5.3, p. 409 If f is convex Consider Example 5f.
