ABSTRACT
A stochastic process is a mathematical concept used to characterize a sequence of random variables (stochastic) that evolve according to another variable, usually time. Each random variable has its own probability distribution function and the variables can either be correlated or not. Each variable or set of variables subject to influences or random effects is a stochastic process. Any time a process (deterministic or essentially probabilistic) is analyzable in terms of probability, it deserves to be called a stochastic process.
