Web9 1.2 Stochastic Processes Deﬁnition: A stochastic process is a family of random variables, {X(t) : t ∈ T}, where t usually denotes time. That is, at every time t in the set T, a random number X(t) is observed. Deﬁnition: {X(t) : t ∈ T} is a discrete-time process if the set T is ﬁnite or countable. fluctis hosting webhost review

Natural evolution is an inherently stochastic process of population dynamics driven by mutations and selection, and the details of such evolutionary dynamics are increasingly becoming accessible via experimental investigation (Barrick et al., 2009; Chou et al., 2011; Finkel and Kolter, 1999; Pena et al., 2010; Ruiz-Jarabo et al., 2003). fluctis rust server

"WebLecture 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.
