1 Introduction to Stochastic Processes
www.kent.ac.uk1.3 Stochastic and deterministic models Stochastic models can be contrasted with deterministic models. A deterministic model is specified by a set of equations that describe exactly how the system will evolve over time. In a stochastic model, the evolution is at least partially random and if the process is run

1 Discrete-time Markov chains - Columbia University
www.columbia.eduStochastic processes are meant to model the evolution over time of real phenomena for which randomness is inherent. For example, X n could denote the price of a stock ndays from now, the population size of a given species after nyears, the amount of bandwidth in use in a telecommunications network after nhours of operation, or the amount of ...
1 IEOR 6711: Continuous-Time Markov Chains
www.columbia.eduwith a continuous-time stochastic process fX(t) : t 0gwith state space S. Our objective is to place conditions on the holding times to ensure that the continuous-time process satis es the Markov property: The future, fX(s+ t) : t 0g, given the present state, X(s), is independent of the past, fX(u) : 0 u<sg. Such a process will
