Abstract. I. 1.2 Stochastic Processes Definition: A stochastic process is a familyof random variables, {X(t) : t ∈ T}, wheret usually denotes time. Home » Given the random nature of future events on financial markets, the field of stochastic processes obviously plays an important role in quantitative risk management. The third edition of Van Kampen's standard work has been revised and updated. stochastic processes.

In the discrete case, the probability density fX(x)=P[x] is identical with the probability of an outcome, and is also called probability distribution. We now consider stochastic processes with index set Λ = [0,∞). Lecture 17 : Stochastic Processes II 1 Continuous-time stochastic process So far we have studied discrete-time stochastic processes.

We can describe such a system by defining a family of random variables, {X t}, where X t measures, at time t, the aspect of the system which is of interest.For example, X t might be the number of customers in a queue at time t. 3.Another way to look at a stochastic process is to consider the stochas-tic process as a function of the sample point !.
