MARKOV CHAINS: BASIC THEORY - University of Chicago

MARKOV CHAINS: BASIC THEORY 3 Definition 2. A nonnegative matrix is a matrix with nonnegative entries. A stochastic matrix is a square nonnegative matrix all of whose row sums are 1. A substochastic matrix is a square nonnegative matrix all of whose row sums are 1.

CONVERGENCE RATES OF MARKOV CHAINS

Markov chains for which the convergence rate is of particular interest: (1) the random-to-top shuffling model and (2) the Ehrenfest urn model. Along the way we will encounter a number of fundamental concepts and techniques, notably reversibility, total variation distance, and

ONE-DIMENSIONAL RANDOM WALKS

post- y process is just an independent simple random walk started at y. But (10) (with the roles of x,y reversed) implies that this random walk must eventually visit x. When this happens, the random walk restarts again, so it will go back to y, and so on. Thus, by an easy induction argu-ment (see Corollary 14 below): Theorem 4.

CONDITIONAL EXPECTATION AND MARTINGALES

conditional expectations behave like ordinary expectations, with random quantities that are functions of the conditioning random variable being treated as constants.2 Let Y be a random variable, vector, or object valued in a measurable space, and let X be an integrable random variable (that is, a random variable with EjXj˙1).

BROWNIAN MOTION - Department of Statistics

Many stochastic processes behave, at least for long stretches of time, like random walks with small but frequent jumps. The argument above suggests that such processes will look, at least approximately, and on the appropriate time scale, like Brownian motion. Second, it suggests that many important “statistics” of the random walk will have lim-

adapted sequence of integrable real-valued random variables, that is, a sequence with the prop-erty that for each n the random variable Xn is measurable relative to Fn and such that EjXnj˙ 1. The sequence X0,X1,... is said to be a martingale relative to the filtration {Fn}n‚0 if it is adapted and if for every n, (1) E(Xn¯1 jFn) ˘ Xn.
