Stochastic Processes

Usage of the term “stochastic process” is not entirely standard. The sense in which we shall use it is probably the most conventional. A stochastic process {Xt, t ∈ T} is a family of random variables defined on a single probability space (Ω,A,P) and indexed by points t in a subset T of the real line. Although it is not necessary to do so, we shall usually associate the parameter t with time. The set T is called the parameter space of the process. If T is a countable set, say T={t1, t2, ...}, then the process {Xt, t ∈ T} is nothing more than a sequence, which was discussed in Chapter 3. We shall be more interested in situations where T is an interval, the most common cases being T = [0, 1], [0, ∞), and (-∞, ∞). If T is an interval, we call the process a continuous parameter process. Unless otherwise stated, we always assume that T is an interval.
