Lecture 5 : Stochastic Processes I 1 Stochastic process A stochastic process is a collection of random variables indexed by time. Depending on the choice of the index set T we distinguish between the following types of stochastic processes: 1. 1.9. The MIGII Busy Period 73 2.4. 2. Stochastic Processes to students with many different interests and with varying degrees of mathematical sophistication. For fixed (the set of all experimental outcomes), is a specific time function. Stochastic Processes and the Mathematics of Finance Jonathan Block April 1, 2008.

THE POISSON PROCESS 59 2 1. Stochastic models play an important role in elucidating many areas of the natural and engineering sciences. independent and identically distributed c.d.f. The set of and the time index t can be continuous or discrete (countably infinite or finite) as well. The Poisson Process 59 22. Financial Calculus, an introduction to derivative pricing, by Martin Baxter and Andrew Rennie. 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. Stochastic processes are ways of quantifying the dynamic relationships of sequences of random events. Otherbooksthat will be used as sources of examples are Introduction to Probability Models, 7th ed., by Ross (to be abbreviated as “PM”) and Modeling and Analysis of Stochastic Systems by … Stochastic processes are also often called random processes, random functions or simply processes. We will cover Chapters1–4and8fairlythoroughly,andChapters5–7and9inpart. Stochastic Processes Let denote the random outcome of an experiment.
