WebDec 20, 2012 · The convergence of the method is theoretically proved for bivariate diffusion processes. We derive explicit expressions for these and other quantities of interest in the case of a bivariate Wiener process, correcting previous misprints appearing in the literature. Finally we illustrate the application of the method through a set of examples. WebOct 1, 2024 · One advantage of Wiener process with drift is that the first passage time can be easily obtained [16], [17], [18]. Moreover, hitting times of bivariate Wiener process models have also been studied [19]. However, a distinct feature of Wiener process with drift model is that the sample path is not necessarily monotonic, which limits its ...
WebJan 1, 2003 · 2. The basic first hitting time model. A general mathematical formulation of a first hitting time model considers a stochastic process in time, {X (t), t⩾0} and an absorbing setH in the state space of the process. The first hitting time is the random variable S defined as follows: (1) S= inf t: X (t)∈H. In other words, the first hitting ...
