21. Models for time series data can have many forms and represent different stochastic processes . 22. This model is an Ornstein Uhlenbeck stochastic process . 23. His research included coding theory, optical communications, cryptography, and stochastic process . 24. Particularly, we can view rumor spread as a stochastic process in social networks. 25. Markov processes form an important class of stochastic processes and have applications in many areas. 26. The study of stochastic processes requires a form of calculus known as the Malliavin calculus. 27. The sequence in which each of the phases occur may itself be a stochastic process . 28. Analysis of blood cells concentrations as long-memory stochastic process , and fractal characteristics. 29. The Poisson statistics underlying the stochastic process . 30. In probability theory p . d . kernels arise as covariance kernels of stochastic processes .
