Stochastic Processes...what is it? My university is offering stochastic processes next semester, here is the course description:
Review of distribution theory. Introduction to stochastic processes, Markov chains and Markov processes, counting, and Poisson and Gaussian processes. Applications to queuing theory.
I'm torn between this course and analysis 2. I'm not sure what stochastic processes deals with, and the description doesn't help. Can anyone explain what you do in such a course? Is it proofs-based? Also, would you recommend this over Analysis 2?
Thanks. 

"Stochastic" refers to topics involving probability -- often the treatment of processes that are inherently random in nature by virtue of being some sot of random function about a random or deterministic variable, or a process parameterized by a random quantity.
For example, Brownian motion is a stochastic process; similarly, the behavior of a LTI system containing a random parameter is a stochastic process (say, the vibration of a spring-mass system, where the spring constant is actually a random variable).
Stochastic calculus requires a strong background in analytical probability theory, which itself requires some notion of measure theory, algebra, and multivariable analysis. Many undergraduate courses will avoid some of the rigorous elements of stochastic analysis, but to really understand it, you will need a decent background in undergraduate analysis through multivariable analysis, Lebesgue theory, and measure theory.
In short, take Analysis II, take Probability, and then consider Stochastic processes if you are interested in it.
