An Introduction To Stochastic Modeling
appliedmath.arizona.eduThis book is intended as a beginning text in stochastic processes for stu-dents familiar with elementary probability calculus. Its aim is to bridge the gap between basic probability know-how and an intermediate-level course in stochastic processes-for example, A First Course in Stochastic Processes, by the present authors.

ocw.mit.eduThe 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.
An Introduction to Stochastic Processes in Continuous Time
www.math.leidenuniv.nlStochastic Processes 1.1 Introduction Loosely speaking, a stochastic process is a phenomenon that can be thought of as evolving in time in a random manner. Common examples are the location of a particle in a physical system, the price of stock in a nancial market, interest rates, mobile phone networks, internet tra c, etcetc.

Discrete Stochastic Processes, Chapter 4: Renewal Processes
ocw.mit.edu158 CHAPTER 4. RENEWAL PROCESSES In most situations, we use the words arrivals and renewals interchangably, but for this type of example, the word arrival is used for the counting process {N(t); t > 0} and the word renewal is used for {Nr(t); t > 0}.The reason for being interested in {Nr(t); t > 0} is that it allows us to analyze very complicated queues such as this in two stages.

galton.uchicago.eduMany 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.
