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-

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).

distributions are equal. Various types of stochastic processes are defined by specifying the dependency among the variables that determine the finite-dimensional distributions, or by specifying the manner in which the process evolves over time (the system dynamics). A Markov chain is defined as follows. Definition 1. A stochastic process X= {X

The remainder of the chapter is devoted to a rather general type of stochastic process called martingales. The topic of martingales is both a subject of interest in its own right and also a tool that provides additional insight Rdensage into random walks, laws of large numbers, and other basic topics in probability and stochastic processes.

To allow readers (and instructors) to choose their own level of detail, many of the proofs begin with a nonrigorous answer to the question “Why is this true?” followed by a Proof that fills in the missing details.
