1.2 Stochastic Processes Definition: A stochastic process is a familyof random variables, {X(t) : t ∈ T}, wheret usually denotes time. That is, at every timet in the set T, a random numberX(t) is observed. Definition: {X(t) : t ∈ T} is a discrete-time process if the set T is finite or countable. In practice, this generally means T = {0,1

Processes 4.1 Stochastic processes A stochastic process is a mathematical model for a random development in time: Definition 4.1. Let T ⊆R be a set and Ω a sample space of outcomes. A stochastic process with parameter space T is a function X : Ω×T →R. A stochastic process with parameter space T is a family {X(t)}t∈T of random vari-ables.
