PROBABILITY AND STOCHASTIC PROCESSES

The mathematics of discrete random variables are introduced separately from the mathematics of continuous random variables. Stochastic processesfit comfortablywithin the unifying model of the text. They are introduced in Chapter 6, immediately after the presentations of discrete and continuous random variables.

Stochastic Processes I - MIT OpenCourseWare

Lecture 5 : Stochastic Processes I 1 Stochastic process A stochastic process is a collection of random variables indexed by time. An alternate view is that it is a probability distribution over a space of paths; this path often describes the evolution of some random value, or system, over time. In a deterministic process, there is a xed trajectory

Stochastic Calculus: An Introduction with Applications

This is an introduction to stochastic calculus. I will assume that the reader has had a post-calculus course in probability or statistics. For much of these notes this is all that is needed, but to have a deep understanding of the subject, one needs to know measure theory and probability from that per-spective.
