Let Tbe an ordered set, (Ω,F,P) a probability space and (E,G) a measurable space. A stochastic process is a collection of random variables X= {Xt;t∈ T} where, for each fixed t∈ T, Xt is a random variable from (Ω,F,P) to (E,G). Ω is known as the sample space, where Eis the state space of the 2015-05-06 · That is, a stochastic process X is a collection where each is an S-valued random variable on . The space S is then called the state space of the process. 4.
