web.ma.utexas.edu1.1 Random variables Probability is about random variables. Instead of giving a precise definition, let us just metion that a random variable can be thought of as an uncertain, numerical (i.e., with values in R) quantity. While it is true that we do not know with certainty what value a random variable Xwill take, we

A discrete-time stochastic process {X n: n ≥ 0} on a countable set S is a collection of S-valued random variables defined on a probability space (Ω,F,P).The Pis a probability measure on a family of events F (a σ-field) in an event-space Ω.1 The set Sis the state space of the process, and the

Renewal processes (since they are arrival processes) can be specified in three standard ways, first,
