Subordinator (mathematics) : ウィキペディア英語版 | Subordinator (mathematics) In the mathematics of probability, a subordinator is a concept related to stochastic processes. A subordinator is itself a stochastic process of the evolution of time within another stochastic process, the subordinated stochastic process. In other words, a subordinator will determine the random number of "time steps" that occur within the subordinated process for a given unit of chronological time. In order to be a subordinator a process must be a Lévy process. It also must be increasing, almost surely.〔 == Definition == A subordinator is an increasing (a.s.) Lévy process.
